In Finland, as a by-product of mining operations, Gypsum is produced and utilized as a soil enhancer and for water conservation. The customer's objective was to maintain a dry environment in this area and effectively manage on-site water removal.
Know moreThe WWT station of Freudenstadt suffered from the problem, that the installed pumps of another maker kept wearing out very fast in the challenging application of a sand trap. Due to the high percentage of sand in the medium to be pumped, normal sewage pumps in grey-cast-iron construction are in terms of material too weak to withstand the abrasion.
Know moreGut Aiderbichl (https://www.gut-aiderbichl.com/en/) has been working for animals since 2001 and is an important institution for animal welfare throughout Europe. More than 6,000 rescued animals live on our home farms in 6 European countries by now, rescued from the most diverse situations. Currently, 35 different species of animals live on our farms. The animal keepers care for them 365 days a year. Gut Aiderbichl sees itself as a meeting place for humans and animals.

Skanska, one of the largest construction groups in the world, was looking for reliable pumps for a water cavern project.
Know moreWe recently welcomed our Finnish market partners to the Tsurumi European headquarters in Düsseldorf for an intensive two-day training programme. 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.

Even the extremely robust and durable Tsurumi pumps require regular servicing to ensure reliable operation over many years. Proper maintenance significantly reduces downtime, lowers operating costs and helps maintain consistently high performance.
Regular inspections, correct operating procedures and timely maintenance of key components such as impellers, mechanical seals and electrodes are essential to keeping your Tsurumi pump in optimum condition.
Recommended Inspection and Maintenance Intervals
Monthly insulation resistance check
The insulation resistance should be checked once a month and remain above 1 MΩ. This protects the motor and electrical components and ensures safe operation.
Six-monthly oil inspection
The oil should be inspected every six months for signs of contamination or decomposition. Contaminated oil can impair lubrication and damage the mechanical seal.
Performance monitoring
Pump performance should be monitored continuously. If output drops by more than 15% compared to normal operation, the pump should be inspected immediately.
Key Components Requiring Regular Attention
Mechanical seals
Mechanical seals should generally be replaced every two years. If oil contamination is detected, replacement should be carried out earlier. Seals, O-rings, V-rings and shaft protection sleeves should also be inspected regularly and replaced when wear is identified.
Impeller
The impeller should be checked and cleaned regularly. Operating the pump within the correct pump curve helps minimise wear and maintain efficiency.
Electrodes
Electrodes must be cleaned regularly and checked for correct function to ensure reliable start and stop control.
Oil maintenance
Oil should be changed every 12 to 24 months. Milky oil is usually an indication that the mechanical seal needs replacement.
Special Requirements for FSP and BER Models
For FSP foam separators, the oil should be checked every 1,500 operating hours or every six months and replaced every 3,000 operating hours or every 12 months. Mechanical seals in the FSP series should be replaced annually.
For BER models, the ejector and air intake system should be inspected monthly to ensure they remain clean and fully functional.
Overhaul Intervals
Even if a pump appears to be operating normally, a complete overhaul is recommended every three to five years to ensure long-term reliability.

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.
