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.

The Grand Paris Express is fundamentally reshaping transport infrastructure across the Île-de-France region. On several of the lines currently under construction, Tsurumi France is playing an important supporting role — including on Metro Line 18, where tunnelling work is steadily advancing.
As the tunnel extends further away from the water treatment point, the challenge of transporting accumulating water increases significantly. Longer distances mean higher pressure losses in the drainage pipes — eventually exceeding the capacity of the pumps initially installed. To maintain continuous water flow to the treatment plant, the construction consortium needed an effective way to overcome these increasing hydraulic demands.
A Booster Solution for Long-Distance Pumping
The site management opted for a booster pump configuration, installing Tsurumi submersible pumps in series and outside the water — a non-standard setup that nevertheless works efficiently thanks to the robust design of Tsurumi pumps.
A key advantage: Tsurumi's original oil-lifter technology, which ensures consistent lubrication and cooling of the mechanical seal, even in demanding or unconventional operating conditions. This eliminates the risk of overheating and ensures reliable long-term performance.
KTZ 422: Power, Pressure and Reliability
To meet the pressure and distance requirements on Line 18, the consortium selected the Tsurumi KTZ 422. This 22 kW powerhouse is one of Tsurumi's most trusted models and is known for:
excellent versatility across applications
the ability to generate high discharge pressure
outstanding durability in abrasive and demanding environments
stable performance even in booster configurations

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.

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:

The so-called PID control (PID: proportional, integral, derivative) plays an important role in the legendary durability and energy efficiency of #Tsurumi pumps.
It offers users a major advantage in process control, as it continuously monitors the deviation between a desired setpoint and a process variable and adjusts the system's response as precisely as possible to the setpoint. In this way, the PID control in our pumps helps to save energy and extends service life.
We have recorded an online #training course on this topic. You can watch it in our #YouTube channel:

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!
Are you also interested in on-site training with our pump professionals? Then please send us an e-mail: sales@tsurumi.eu

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.

Recently, our colleagues at @Tsurumi USA, in collaboration with Zone Industries, supported the development of a new launch pad for space rockets with our high-performance power units.
When a rocket is launched, its engines emit large flames. To cool the rocket, protect the concrete launch pad and absorb the resulting sound energy, a spray system releases thousands of litres of water during the launch. Most of the water turns into vapour, while the rest has to be pumped out.
To avoid this problem of evaporation, a newly designed spray system nicknamed the 'Booster Bidet' has been developed. This system delivers a powerful jet of over 360,000 litres of water within eight seconds. The water is fed through pipes from tanks pressurised with nitrogen. Finally, #Tsurumi high-pressure pumps from the KRS and LH series discharge the overflow water from the flame trench. In this way, the site is quickly prepared for repeated start-up cycles.
With more frequent launches into space, Tsurumi's pumps will play a relevant role in keeping the infrastructure intact and the missions on schedule.
The specifications of the KRS and LH series can be found on our website, of course. If you are interested in these pumps, we will be happy to advise you - just contact us via e-mail: sales@tsurumi.eu

The inrush current is generally limited during the soft start of a motor. Among other things, this prevents a voltage dip under heavy loads. At the same time, the mechanical components in the device are protected from excessive acceleration.
For these reasons, we use soft starters in our #Tsurumi pumps - whenever the direct start or the star/delta start are not suitable.
In a training video, we show how we use them to extend the service life of our pumps. You will learn more about:
- the operating principle of the soft starter,

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.

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:

Our stand has been dismantled, our contractor and #wastewater pumps are on their way back to our warehouse at the #Tsurumi European headquarters in Düsseldorf. What remains are the memories of a very good week at #BAUMA and numerous interesting conversations with our trade fair guests!
Our Tsurumi team, supported by many of our European market partners, spent seven intensive days experiencing how important high-performance, durable and reliable pumps are to many companies in the construction industry. We were able to explain the quality and advantages of Tsurumi pumps in many discussions. We also learnt time and again from customers how well they can work with our solutions. This also includes our digital analysis, monitoring and control system Tsurumi Connect.
We are already looking forward to the next #bauma and the many other trade fairs where you can experience Tsurumi live in the meantime. But for now, we would like to thank you for your visit - see you next time!
#stronger4longer #BAUMA2025 #BAUMA25
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!
#stronger4longer #BAUMA25
When the rade fair BAUMA starts next Monday in Munich, it's worth visiting our stand A6.338 just to see #Tsurumi Connect. This is our digital system that allows you to network, control, monitor and analyse the parameters of analogue pumps and other construction machinery.
A fascinating innovation that our technology experts will be presenting to you at #BAUMA25 - and in advance in a video on our #YouTube channel. In the video, we use a few examples to demonstrate how to connect the Tsurumi Connect Box to a pump and sensors. The Tsurumi Connect Cloud is also a topic: https://youtu.be/Q3tDiVZJz0c?si=jqVJuzQrjWa5W6VB
Enjoy the film. If you have any questions about our digital solution or want to know how to use it optimally for your construction project, please contact us - either at BAUMA in Hall A6 or by email at sales@tsurumi.eu. You can also find more information online: www.tsurumi-connect.eu

Discover our #Tsurumi LH12185D! This version of the LH series has a special impeller and currently the largest motor in our contractor pump range: the 2-pole, 185 kW motor impresses with effortless power delivery for tough #dewatering work in #mining and other construction projects.
The LH12185D offers a maximum flow rate of 14000 l/min and a maximum delivery head of 85 m - ideal for mining and #tunnelling work. The special feature: The LH12185D can suck in large quantities of water from both the upper and lower side of the double suction impeller. This reduces the thrust load, which extends the service life of the bearings and increases the stability of the pump operation. To withstand the tough operating conditions, the impeller is made of wear-resistant, high-chromium cast iron.
Details on the LH series can be found on this website: https://www.tsurumi.eu/products/drainage/lh-161

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:

May we introduce? The powerful and robust #Tsurumi NKZ45.5 and NKZ611! The NKZ are sand and sludge pumps made of cast iron and driven by a 4-pole motor. The agitator mounted under the impeller supports the smooth pumping of water with settled solids. The spiral-shaped pump housing ensures the smooth passage of foreign matter in the medium.
The Tsurumi NKZ45.5 with 5.5 kW motor power offers you a maximum output of 2000 l/min and a maximum delivery head of 18.7 metres. The Tsurumi NKZ611 has even more power in store: with twice the motor power of 11kW, it pumps an impressive flow rate of up to 3,950 l/min over a maximum delivery head of 21.7m - that's about as high as a six-storey residential building.
The specifications of the NKZ series can be found here on our website:
https://www.tsurumi.eu/products/sand-and-slurry/nkz-179
At #Tsurumi, we attach great importance to products that enable our customers to pump even difficult-to-handle liquids. These include corrosive liquids, liquids at high temperatures and seawater.
A very special series for this is the Tsurumi LH-14 / LH-W-14 series made of stainless steel! It is now finally available from stock for customers in Europe.
The LH-14, like the LH-W-14 equipped with two impellers, is highly corrosion-resistant. All parts that come into contact with the medium are made of 316 stainless steel so that they can withstand extreme applications in the construction industry and in #mining.
The stainless steel LH is so tough that it would probably inspire respect even from famous fighting robots universe!

Pumping #wastewater that contains contaminants with fibrous substances? Where conventional pumps fail, the #Tsurumi CZ series is in its element: The submersible pumps have a cutting and shredding function in a unique design: A heart-shaped suction opening with a sharp-edged fixed cutting blade combined with a semi-open channel impeller, which is also equipped with two sharp-edged blades, results in a scissor-like shredding mechanism.
This innovation enhances the CZ pump's ability to deal with larger debris. Clogging of the pump is thus prevented by a mix of shredding and crushing.
Attention! These models are now available from stock in Europe:
100CZ45.5 (5.5 kW), 100CZ47.5 (7.5 kW), 100CZ411 (11 kW) and 100CZ415 (15 kW)
The CZ series is presented here in the video:

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.
