Three Trade Fairs, One Month, Many Pump Solutions: Meet Tsurumi in Germany

Reliability, durability and exceptionally long service life have made Tsurumi pumps highly successful in demanding applications around the world. Unfortunately, market success also attracts imitation. Some suppliers offer copies of Tsurumi high-performance pumps that may look similar at first glance – but appearances can be deceptive.

Tsurumi pumps are designed to prevent overheating during dry running and protect their sealing surfaces from damage. This allows them to operate reliably around the clock, even when water levels are low.
For continuous operation, however, energy efficiency is also an important consideration. That is why Tsurumi offers contractor pumps equipped with electronic level control. The pumps start automatically when the water reaches a predefined level and switch off again as soon as the water level drops below it. This ensures that the pumps only operate when they are actually needed.

Pump blockages are one of the most common reasons why submersible pumps lose performance or stop operating altogether. Solids accumulating around the impeller, suction plate or discharge pipe reduce hydraulic efficiency, increase wear and can eventually lead to costly downtime.
Fortunately, many blockages can be prevented through proper pump selection, correct system design and regular maintenance.

Selecting the right sewage pump is a key factor in ensuring reliable wastewater and industrial dewatering operations. Every application places different demands on pumping equipment, whether it involves fibrous materials, abrasive solids, sludge or corrosive liquids. Choosing the appropriate pump and impeller configuration helps reduce clogging, minimise wear and improve long-term system performance.

Submersible pumps are often required to perform under the toughest operating conditions. Whether in mining, construction, wastewater management or industrial applications, they must handle abrasive slurries, corrosive liquids and demanding duty cycles every day. Without the right selection, installation and maintenance, these harsh environments can significantly reduce pump life and increase operating costs.
Fortunately, there are proven ways to maximise reliability, minimise downtime and extend the service life of your Tsurumi submersible pump. Here are six practical recommendations from our experts.

A major milestone is approaching in one of Berlin's most important water infrastructure projects. Construction of a new 30-metre-deep stormwater overflow basin began in January 2025, and after around 18 months of continuous dewatering, the project is now preparing for its first test flooding.
Throughout the construction phase, groundwater and surface water have been reliably collected in pump sumps and removed using Tsurumi submersible pumps. For this demanding application, our trusted market partner Biergans Pumpen-Vertrieb GmbH selected Tsurumi's robust LH series, which has delivered virtually wear- and maintenance-free operation under challenging site conditions.
As the project progressed and operating conditions changed, the originally installed LH 23.0 was complemented by the even more powerful LH 25.5, ensuring maximum performance and reliability throughout every stage of construction.
With the completion of the basin now in sight, Berlin's impressive Stormwater Overflow Basin No. 4 is almost ready for its test flooding. The drainage process will once again rely on Tsurumi technology, with two GPN622 pumps equipped with protective cages standing by for operation.
From the very beginning, Biergans Pumpen-Vertrieb GmbH has supported this flagship project with premium Made in Japan pump technology and outstanding technical expertise. The upcoming test flooding marks another significant milestone as this major infrastructure project moves towards completion.
Once operational, the underground basin will provide a storage capacity of 16,750 cubic metres—equivalent to approximately four and a half modern Olympic-sized swimming pools. It forms an important part of Berliner Wasserbetriebe's long-term Storage Capacity Programme, designed to strengthen Berlin's stormwater management infrastructure and help protect the city's waterways during heavy rainfall events.

Many cases of overheating motors or underperforming pumps are not caused by the quality of the motor itself. In fact, the root cause is often found in the electrical power supply.
A common mistake during troubleshooting is measuring the electrical values when the pump is not operating under full load. In such situations, the readings may appear to be within standard limits, while the actual problem only becomes visible during normal operating conditions.
To ensure accurate diagnostics, the following points should always be considered:
1. Measure only while the motor is running
Electrical measurements should always be taken when the motor is in operation to obtain meaningful results.
2. Check for voltage drop
Undersized conductors or excessively long cable runs can cause significant voltage drops under heavy load conditions.
3. Measure all three voltage pairs
Check the U, V and W phase pairs. Standard operating voltage is typically between 380 and 400 volts.
4. Monitor voltage balance
Large voltage differences between phases can lead to increased motor temperatures and premature failure.
5. Isolate and inspect each phase
Disconnect and test each phase individually to identify potential mechanical blockages or load-related deviations.
6. Perform a warm-up test
High starting currents combined with poor electrical connections can quickly reduce system performance and efficiency.
Understanding the relationship between power quality and pump performance is essential for reliable operation and long service life. Proper electrical testing under real load conditions can help prevent unnecessary downtime, reduce maintenance costs, and improve overall system efficiency. Very important: Electrical work must only be performed by qualified electrical personnel.

Understanding how a pump operates within a system is essential for achieving both efficiency and reliability. Tsurumi highlights the importance of pump performance curves as a key tool for selecting and operating pumps სწორly—helping to avoid excessive wear, vibration, and premature failure.
A pump performance curve shows the relationship between flow rate and head pressure, indicating how a pump performs under different conditions. By identifying the correct operating point—defined by the required flow rate and Total Dynamic Head (TDH)—users can determine whether a pump is suitable for their system. TDH includes both static head (vertical lift) and friction losses within the system.
At the center of efficient operation lies the Best Efficiency Point (BEP), where the pump delivers maximum hydraulic efficiency with minimal energy use. Operating near the BEP ensures balanced internal forces, smooth performance, and reduced mechanical stress. Selecting a pump that runs close to this point under normal conditions is key to maximizing efficiency and extending service life.
Running a pump far outside its BEP can lead to serious issues. Imbalanced forces inside the pump increase stress on components such as bearings, seals, and shafts, potentially causing premature failure. In addition, hydraulic instability may occur, leading to cavitation—where vapor bubbles form and collapse—damaging internal components and accelerating wear.
Efficiency can also decline over time due to wear, deposits, blockages, or insufficient maintenance. These factors can shift the operating point away from the BEP, increasing energy consumption and reducing performance. Regular inspection, cleaning, and maintenance are therefore essential.
To ensure optimal performance, it is recommended to regularly verify the actual operating point using flow and pressure measurements. If necessary, system adjustments—such as modifying resistance or valve settings—can help bring the pump back into its optimal range.
Conclusion: Correct interpretation of pump curves, accurate system design, and continuous monitoring are crucial for maintaining energy-efficient and reliable pump operation.

Six participants from our authorised dealer Machinery Oy and its service partner Flowplus Oy took part in the practical course, which combined in-depth product knowledge with hands-on experience.
Following a welcome dinner the evening before, the training began with an introduction to the Tsurumi brand and its comprehensive product portfolio. Our technical experts Stefan Himmelsbach, Sandor Rostas and Fernando Morales guided the participants through the programme with great enthusiasm and expertise.
A key focus was placed on the unique features of Tsurumi high-performance pumps, including the double internal mechanical seal and the oil lifter – both developed in-house by Tsurumi engineers and technicians. Further topics included the function of the motor protection plug, checking the correct direction of rotation, identifying pumps with missing or damaged nameplates, and an overview of pressure booster and jet pump systems. Participants also gained valuable insights into the capabilities of the Tsurumi Connect digital monitoring system.
In addition to the theoretical sessions, the training placed strong emphasis on practical application. Together with our Finnish guests, used pumps were examined and their condition assessed. Participants were able to dismantle individual units themselves, reassemble them professionally and carry out functional testing afterwards.
After two informative and engaging days filled with technical knowledge, practical tips and valuable exchange, we said goodbye to our Finnish colleagues. We would like to thank all participants for their commitment and look forward to continuing our successful collaboration in the future.

When water rises unexpectedly, there is no room for delays. In civil engineering, tunnel construction, drainage projects or flood situations, reliable pump technology must be available immediately. Downtime can lead to costly damage, safety risks and project delays.
While many manufacturers rely on order-based production and therefore struggle with long delivery times, Tsurumi takes a different approach. Almost all of the company's more than 500 pump models are available directly from stock, giving customers a decisive time advantage in critical situations.
Stock Instead of Waiting Time
"We have made a virtue out of necessity," explains Daniel Weippert, Managing Director of Tsurumi Europe GmbH.
"As delivery times from our central factory in Japan are long, we must ensure sufficient availability in Europe."
To achieve this, Tsurumi maintains a six-month supply for the European market in its central warehouse in Antwerp. In addition, a three-month stock for Germany, Austria and Switzerland is held in Düsseldorf. Spare parts are also kept comprehensively in stock – not based on sales frequency, but according to practical necessity. This ensures that the full product range can be supported at all times.
A Decisive Advantage in Time-Critical Applications
Immediate availability is particularly crucial in construction drainage, special civil engineering, emergency situations and accident response.
"When an excavation pit fills up or heavy rainfall is forecast, there is simply no time to wait weeks for equipment," says Weippert. "In such cases, we deliver within hours via express direct shipment."
This logistics strategy enables Tsurumi to respond quickly and reliably whenever powerful pump solutions are urgently required – whether for planned projects or unforeseen emergencies.

In certain applications, customers deliberately choose to install their Tsurumi pump dry next to a sewage or wastewater tank. This setup offers clear advantages: maintenance work becomes faster, safer and more convenient. However, one crucial factor must be considered in dry installations – reliable motor cooling.
Submersible pump motors are normally cooled by the surrounding liquid. When a pump is installed permanently outside the tank, this natural cooling effect no longer applies. Without an appropriate cooling concept, overheating and premature wear would be unavoidable.
This is where Tsurumi's intelligent pump design comes into play.
Built-in cooling – even when installed dry
Tsurumi pumps designed for dry installation feature a proven cooling system:
A cooling jacket guides the pumped liquid around the motor to dissipate heat effectively
A bypass system ensures a constant flow into the cooling jacket
The motor remains reliably protected against overheating, even when the pump is not submerged
Why this matters for your operation
Reduced maintenance effort: Dry installations improve accessibility and shorten service times
Longer service life: Stable cooling protects the motor from thermal stress
Higher operational reliability: Correct cooling prevents unplanned downtime and costly repairs
To learn more about how cooling works in dry-installed Tsurumi pumps, watch our dedicated training video on YouTube.

While much of the Lyon–Turin tunnel is being excavated using tunnel boring machines, several sections rely on traditional blasting techniques. Here, workers drill deep holes into the rock, fill them with dynamite, and detonate them to advance the tunnel. The loading drill shown in our photo breaks through the rock face, allowing the explosives to be placed precisely.
Each blast, however, brings new challenges: fresh water inflows emerge from the surrounding rock, carrying dust, metal particles, and coarse debris. This mixture must be pumped out continuously to keep the site safe and operational. The conditions are some of the toughest imaginable for any pump:
24/7 continuous duty
Occasional dry running
Highly abrasive water containing rock and cement particles
Strong vibrations and occasional heavy impacts
In this demanding environment, Tsurumi pumps show exactly why they are trusted worldwide in tunnel construction. They are:
Exceptionally durable and high-performing
Extremely robust and wear-resistant
Simple to service and maintain
Whether you need compact units or high-capacity powerhouses, Tsurumi offers a full range of pumps engineered for the toughest underground conditions.

Water quality has a direct impact on the performance, durability, and maintenance requirements of pump systems. Poor water conditions or specific characteristics can cause failures, increase repair costs, and significantly reduce the service life of a pump. Understanding the type of water in use is therefore essential for ensuring long-term efficiency.
Common Water Types and Their Effects on Pumps
Saltwater
Saltwater environments place extreme demands on pump materials. High salt concentrations can quickly cause corrosion and damage if equipment is not properly maintained. Submersible pumps in coastal or marine environments require robust construction and corrosion-resistant materials.
Freshwater
While freshwater is generally less aggressive, it still presents challenges. Neutral pH levels slow corrosion, but long-term exposure can still affect metal components. Additionally, mineral deposits and residues can clog inlets and reduce flow efficiency.
Contaminated Water
Contaminated or polluted water often contains sediments, oils, chemicals, and solids. These impurities accelerate wear, impair hydraulic performance, and may damage critical internal components.
Acidic Water
Acidic liquids, even in low concentrations, can attack metal surfaces and seals. Incorrect material selection may lead to leaks, corrosion, and unexpected downtime.
Why Tsurumi Pumps Are the Right Choice for Any Water Type
Selecting a pump that matches the water quality is essential for efficiency, reliability, and long service life. Tsurumi pumps are specifically engineered to handle a wide range of challenging environments—saltwater, freshwater, contaminated water, or acidic conditions.
Key advantages include:
Corrosion-resistant materials:
Tsurumi uses durable alloys such as 316 stainless steel and advanced composite materials designed to resist aggressive water conditions.
Protective coatings:
Critical components feature special coatings that reduce wear and provide long-term protection.
Optimized engineering:
Every design element—from mechanical seals to impeller geometry—is built for maximum resilience against corrosive or abrasive liquids.

In the Gorges du Verdon, one of France's most famous gorges, an ambitious construction project is currently underway: a 250-metre bypass is being built to secure a tunnel. Before excavation could even begin, a major challenge had to be overcome — the diversion of an impressive 180,000 cubic metres of water.
The team from Tsurumi France took on this demanding task with precision and determination. Over the course of a week, the team prepared the site by lowering three series of Tsurumi pumps 22 metres below ground level, installing pipes for horizontal water drainage (with a 21-metre height difference), setting up settling basins, and completing all electrical connections.
On Tuesday, 3 September, at 8:30 a.m., the pumps were started:
One GSZ, two KRD and three LH models, each designed for extreme operating conditions, worked continuously and reliably until Thursday, 5 September, at 1:30 a.m. By that time, 90,000 cubic metres of water had already been successfully pumped out — the remainder drained away naturally by gravity.
This impressive operation once again demonstrates the reliability, strength and endurance of Tsurumi pumps – even under the toughest environmental conditions.

This coming Friday, September 26, at 11 a.m. (CEST), take about 30 minutes to join us for a new #Tsurumi online training session! Our technical experts will discuss the importance of pipe type and inner diameter in the design of submersible pumps.
Why is this so important for you? Because the choice of pipe type and internal diameter determines the efficiency and service life of submersible pumps. This is because they influence the hydraulic resistance and flow conditions.
Empirical data from practical experience shows that pipes with too small a diameter or made of unsuitable materials lead to increased pressure loss and, in extreme cases, to cavitation. The pump becomes overloaded, and its service life is shortened.
For example, a pipe that was too small (DN50 instead of DN80) in a sewage system doubled energy consumption and caused frequent failures due to overheating. Conversely, a correctly dimensioned pipe in a similar application reduced maintenance costs by 30% and extended the service life of the pump by two years.
In the live training session, we explain how to find the right pipes for your Tsurumi pump and the respective application. This is an important topic that you should not miss. We appreciate your interest! Use this link to join the free livestream on September 26:

In Italy, at our partner Dragflow we trained 12 experts and customers on #Tsurumi pumps over two days! The comprehensive programme included a large theoretical section and, of course, practical work on selected pumps!
First, we provided information on:
- our company
- the Tsurumi product portfolio with technical features
- differences in hydraulics
- applications in tunnel construction
- special applications such as booster/jetting
- our TRN submersible aerators
For the practical part, we randomly selected three rental pumps that had been returned shortly before. Therefore, we did not know what condition they would be in until we opened the pumps.
An LSC1.4S ran continuously for many years without maintenance, which is normal for Tsurumi pumps. Everything, including the motor, was in good condition; only the check valve and base plate had to be replaced.
An LH311W had been operating in salty seawater for two months. It was in good condition, only the sacrificial anodes in the strainer had to be replaced.
And in the case of a KRS822 after 12 months in salt water, the electrical parts were also in good condition. The hydraulic parts had to be replaced and serviced due to prolonged use in salt water.
The participants enjoyed dismantling and inspecting the pumps and carrying out the maintenance tasks. And we were happy to once again impart valuable knowledge about pumps!

With the #Tsurumi guide rail systems, our pumps can be easily connected, moved up and down and removed again. Each system consists of rails or channels that connect the pump to the pipework. When the pump is lowered or raised, it slides along the rails - connected to an outlet pipe.
The guide rail systems simplify maintenance and reduce the risk of extended downtime. Unlike fixed pipework systems, which can take several hours to install and assemble, a pump on a guide rail is ready for operation more quickly.
Guide rail systems are particularly important in wet wells or sumps. For lifts deeper than four and a half metres, we recommend using a direct guide rail mount for added stability and smoother pump removal. Material selection is an important factor when choosing a guide rail system. Depending on the type of liquid being pumped, the rails can be made of stainless steel, cast iron or high-density polyethylene.
We are happy to answer your questions about the different types of our guide rails. Simply write to us at: sales@tsurumi.eu

#Tsurumi pumps can be operated automatically in two ways: Via activation by a float switch or via an electrode.
Float switch
Float switches are often used where the performance of a pump is to depend on the water level. The switch is located in a piston that floats on the surface of the water. When the water level rises or falls, the float moves into position and opens or closes an internal switch that controls the pump's output.
Electrode
An electrode sensor recognises water based on its conductivity. It activates the pump when it is submerged under water. Unlike float switches, electrode sensors do not rely on mechanical movements. Instead, they utilise the natural conductivity of water to trigger an electrical reaction. Electrode sensors are permanently mounted directly on the pump. Ideal for installations where space is limited or a float mechanism could be blocked.

The #NAK agricultural and farming machinery exhibition in Mezőfalva/Hungary, which we have also announced on our website, has been cancelled! The trade fair, at which our Hungarian market partner #VERBIS also wanted to present #Tsurumi high-performance pumps, was actually scheduled to take place this Wednesday and Thursday (4/5 June). However, there are currently outbreaks of foot-and-mouth disease in the region. In order to minimise the risk, the National Chamber of Agriculture (NAK) and the National Association of Dealers in Agricultural Equipment and Machinery have decided to cancel the fair.
If you are interested, you can of course experience Tsurumi pumps live not only at trade fairs, but also with our market partners and us: https://www.tsurumi.eu/about-tsurumi/distribution-network-15. Feel free to contact the experts on site - in Hungary, for example, our colleagues from VERBIS: https://www.verbis.hu/

Time is of the essence on the construction site of the future underground railway in #Toulouse, France. There is no time to chase numbers - especially when it comes to the quantities of #water to be pumped, the performance or the traceability required by the authorities. #Tsurumi Connect helps with all these issues:
Our digital system collects real-time data from the connected pumps, checks the direction of rotation and phase, monitors operating costs, enables preventive maintenance of the pumps and issues push notifications in the event of problems so that a quick response can be made.
Our colleagues from Tsurumi France installed the system on the large construction site and coupled it with a flow meter. The result: a reduced operational load, better responsiveness and more transparency for the teams on site and the site managers.
Details about Tsurumi Connect can be found here: https://www.tsurumi-connect.eu/

Did you miss #BAUMA2025 in Munich? Too bad, because then you also missed the #Tsurumi highlights that we presented in Munich this year. These mainly included our contractor, wastewater and sewage pumps, but also a lot more - such as a smart booster installation with pumps connected in series, which we used to show how you can digitally network analogue pumps with Tsurumi Connect. This allows you to control, monitor and analyse your pumps or other connected machines.
To give you an impression of the trade fair, our video summarises seven exciting days at the fair in 80 seconds:

Are you already looking forward to #BAUMA in Munich? This world trade fair for the construction industry only takes place every 3 years. As of today, the time has come again, and of course #Tsurumi is there.
We will be showing a large selection of contractor, #wastewater and sewage pumps at our stand A6.338 - and more: using the example of a smart booster installation with pumps connected in series, we will show you how you can digitally network analogue pumps: with Tsurumi Connect. This allows you to control, monitor and analyse your pumps or other connected machines. Furthermore you can experience for example the #Tsurumi CZ - our most powerful #sewage pump - at our booth. It has a special cutting configuration to prevent hard and fibrous solids from causing blockages. We will also be exhibiting TRN submersible aerators and MMS agitators for the wastewater sector at #BAUMA - and of course our compact wonders, the LSC flat puddle suckers. These remove #water down to a residual moisture content of one millimetre. In addition, despite their power, the LSC units are real lightweights so that they can be carried quickly to any job site.
Our place of operation from 7 to 13 April is #BAUMA2025 - hopefully yours too: We will welcome you to stand A6.338 with a Japanese ambience including a cosy bar and our tatami lounge. We look forward to your visit!

A technological highlight in over 100 years of #Tsurumi history is the development of the oil lifter in 1998, which is partly responsible for the legendary reliability and reliability of our units. Our engineers in Japan invented this component, which is positioned around the mechanical seal and ensures optimum lubrication of the upper seal faces. This works even if the lubricant is reduced to up to 1/3 of the nominal volume.
Pumps without oil lifters displace the lubricating oil to the outside. This quickly leads to bearing damage. In all Tsurumi pumps, the oil lifter ensures that the mechanical seals are permanently lubricated. This extends the service life of the mechanical seal. In addition, the combination of double inner mechanical seal and oil lifter prevents seal damage during dry running. Since then, even when a Tsurumi is aligned horizontally, the seal faces remain lubricated, which contributes to the longevity of the pump and ensures maximum performance when working in any position.
This video shows what makes the Tsurumi oil lifter so unique:

Damaged cables are one of the main causes of pump failures. This is because capillary action can cause water to penetrate the cables, leading to insulation breakdowns, short circuits and costly repairs.
We at #Tsurumi have something to prevent this: our innovative anti-wicking cable entry system! This means that moisture can no longer penetrate, even with damaged cables. You benefit from minimal maintenance and maximum efficiency.
To see how the anti-wicking system is designed and how it works watch this video:

The process water of a plastic recycling plant naturally has a high proportion of plastics. This water must be collected and pumped by suitable pumps. Conventional shredding pumps repeatedly failed to perform this task. The solution for the customer was to switch to the hashtag#Tsurumi C series - one of the most reliable series in the market.
The 80C21.5 were able to pump the medium without any problems. A total of eight cutter pumps were installed in different basins to gradually remove the solids from the water so that it can be fed back into the recycling process.
All pumps are controlled by level sensors that keep the water in all containers at the same level, regardless of changes in the water inflow. By keeping the water level low, the pumps can collect more of the light solids that tend to accumulate on the water surface.
We have linked the specifications of the C series for you in the comment below this post.
