Tsurumi (Europe) GmbH

The British distributor Obart from Maidstone in Kent now trades as Tsurumi Pumps UK. This means that the Japanese manufacturer now has six sales companies in Europe. This was announced by Tsurumi’s European headquarters in Düsseldorf/Germany. The change of name took place on 1st September 2023, following Tsurumi’s entry as majority shareholder in the dealer in 2020.

Since 1972, Obart has been supplying the United Kingdom with pumps for dewatering and sewage treatment. Barely three years later, the first Japanese pumps were added to the supply and rental programme. Matthew Hill, Managing Director at Tsurumi Pumps UK, said that the units had become popular due to their high performance, reliability and ease of maintenance. The high hydraulic-energy efficiency, the biodegradable lubricating oil and the new options for remote monitoring and control of the entire water logistics are further aspects. They form the basis for the success of the brand.

“This move will have a positive impact on our customers and enable us to expand as a market-leading supplier of dewatering pumps,” Hill announced. Workforce, management and company headquarters will remain unchanged, he said.

With Tsurumi Pumps UK, Tsurumi Europe now runs six subsidiaries. The manufacturer is also present in Belgium, Germany, France, Sweden and Spain. In addition, there is a dense network with many hundreds of dealers and service points.

Tsurumi is considered the world’s largest manufacturer of dewatering pumps for the construction industry. Since its foundation in 1924, the company has specialised exclusively in technologies for water utilisation.

The product range includes pumps for clear, mud and waste water, build as submersible units or for dry installation. In Europe, more than 500 types are available with flow rates of up to 30 m³/min or 216 m maximum head. The company is committed to providing the best service in the industry. “Stronger for longer” is the brand’s slogan.

The headquarters are located in Osaka/Japan. In Kyoto, Tsurumi operates the industry’s largest manufacturing facility with an annual capacity of one million pumps. 860 employees generate an annual turnover of around 350 M€.

The Ukraine is groaning under the consequences of the war, but is already thinking about reconstruction. A Ukrainian delegation therefore recently visited the European headquarters of the Japanese pump manufacturer Tsurumi in Düsseldorf, Germany.

The focus was on dealing with the damage caused by the Russian war. This is affecting life and the infrastructure in many places in the country. For example, the destruction of the Kakhovka dam on the Dnipro River led to huge floods. As a result, coal-fired power plants had to be closed due to flooding. Like many other things, they are to be dewatered as quickly as possible.

As the world’s largest manufacturer in the industry, Tsurumi is considered an important address. Not least because it does not manufacture to order, as is customary in the industry, but keeps almost all pumps ready for delivery in its European warehouses.

The delegation of technology experts and decision-makers learned about the technical option for the removal of clear, dirty and waste water. Tsurumi’s pump programme for the European market includes about 500 models delivering up to 30 m3/min or 216 m head.

An important aspect for the Ukrainians: the pumps should be self-serviceable and require little effort to maintain – a key feature that almost all Tsurumis fulfil. Some of the participants wanted to experience this right on site: they carried out the maintenance of a pump unit themselves, following instructions given by Tsurumi personnel. Even before the war, Tsurumi supplied pumps to Ukraine.

At Steinexpo 2023 in Germany, exhibitor Tsurumi will be showing not only universal pumps but also heavy-duty equipment for harsh scenarios: when deep pits have to be dewatered or a lot of sediment is involved.

The manufacturer is at home on this terrain and knows how to deliver. Whether for tunnels, mines or special civil engineering: In Europe’s largest basalt quarry, the Düsseldorf-based company will demonstrate this year how dewatering works in extreme environments.

Among other pumps, the GPN series will be on display. For the heavy slurry pump, the manufacturer relies on a housing made of thick-walled grey cast iron GG20 to counteract abrasion. The spiral-shaped water flow through the housing is a plus when it comes to avoid blockages – after all, soil and sludge should be able to be pumped along without any problems, even in large quantities. An agitator on the shaft swirls everything to make it flowable. Grain sizes up to 30 mm are insignificant, they said. To reduce clogging, the impeller and suction plate are made of chrome cast iron. The series comprises six models. They achieve flow rates of up to 9000 l/min and heights of up to 34 m. The motors have an output of between 5,5 and 37 kW.

With its LH pump shown at Steinexpo, the manufacturer goes even further, or rather: deeper. The high-pressure pumps of this series can pump water up to 177 m vertically. The two-stage LH-W even goes up to 216 m – Tsurumi is the only supplier worldwide in this field. This means that a single pump is all that is needed – instead of several pumps, which would be costly to connect in series.

For the Steinexpo in Nieder-Ofleiden, Tsurumi has also packed a whole series of single-phase pumps. All of them are universalists, some are even suitable for residue-free pumping out of containers and puddles – i.e. down to a residual level of 1 mm. The manufacturer shows some units in live wet operation. Cutaway models reveal to experts what the pumps are capable of. More on Tsurumi.eu or Youtube.

Pump manufacturer Tsurumi is equipping several pump series with ultra-hard chromium impellers free of charge. A technical step forward for users, because with many manufacturers the critical component is only available as an expensive option – if at all.

Once again, Tsurumi wants to define the standard in the market. The Japanese company with its European headquarters in Düsseldorf, Germany, is considered the world’s largest manufacturer of dewatering pumps for the construction industry.

Hard as a Katana sword
The impeller is the pump’s propeller, so to speak. It is located on the shaft at the intake opening and “shovels” the water into the unit. Enormous forces act at this point. They are caused by the high rotational speeds and abrasive sediments in the water. Tsurumi even tolerates hard rock up to 30 mm grain size at a flow rate of up to 12 tonnes per minute in the chromium equipped pump models.

The high chromium content of up to 28 per cent makes the impellers extremely wear-resistant. The material is five times more resistant to abrasion than grey cast iron or stainless steel, the manufacturer said. Tsurumi gives exact specifications: The hardness according to Rockwell, the internationally used unit of measurement for technical materials, is 51. For the pumps of the GY series it is even 60.

This puts the Tsurumi impellers on a par with the legendary Japanese Katana blades, a reference in terms of hardness and cut resistance.

Vortex impeller plus wear plate
Tsurumi always uses semi-vortex impellers. In combination with its wear plates, the manufacturer achieves hydraulic efficiency levels similar to that of closed impellers – without their disadvantages. Another plus: by readjusting the wear plate, the optimal pressure point of the pump can be set even when the abrasion is already far advanced. The impeller can thus run significantly longer. This reduces the costs and maintenance times of the pump.

Which pumps do companies rely on when it comes to removing dirty water? The pump manufacturer Tsurumi has taken a look – these are the best-sellers of 2022.
Moving water from A to B: What seems simple is sometimes a feat of strength. The Japanese pump manufacturer Tsurumi has been meeting this challenge since 1924. With great success, because the brand with the blue water vortex in its logo is considered the world market leader in the industry. The product range for the EU market alone includes around 500 models with flow rates of up to 30 m³/min. The company was particularly pleased about last year, because it was able to repeatedly increase its turnover. Tsurumi does not publish any concrete figures. But the ranking volumes start “with four digit figures”, the company announced in Düsseldorf.

The smallest is the biggest

Of all things, the smallest model of the manufacturer, the “Family-12”, holds the top position in deliveries. This is a universal submersible dewatering pump with a motor power of only 100 watts, but with a capacity of 80 l/min. The core target group includes crafts in the construction sector where “things can go wrong”, meaning, where residual water has to be collected. Where tanks have to be emptied. Or cellars that have filled up with excessive amounts of rain water.

The pump is therefore designed as a residue water pump that can pic up water from flat surfaces down to a water level of just 1 mm.  Tsurumi’s second-placed model, the LSC, falls into the same category. It offers much more and is part of the basic equipment of many fire brigades. Remarkably, the more powerful newest edition, just introduced in 2022, advanced to one of the most successful market launches of recent years.

Third place is occupied by a pump that bridges to the category of units used for groundwater dewatering tasks, which is Tsurumi’s core segment. The LB series is good for up to 440 l/min and heads of up to 17 m. The HS series is also in this range, with similarly considerable numbers.

“Heavy boys” are all three-phase

The next ranks are occupied by the “real” construction pumps of the market leader. These are the three-phase units with powerful motors that are also used for the heaviest dewatering tasks, such as in mines and tunnels. This is where the KTZ series really shines – and sold best: three letters demonstrating all what Tsurumi stands for – and what is echoed in the company slogan “Stronger for longer”.

The KTZ is a powerful, robust pump with flow rates of up to 3,960 l/min that pushes water vertically upwards to 71 metres. It even swallows chunks of 20 mm hard rock, without being prematurely capitulated by abrasion. The pump has an ingenious motor cooling system, because the pumped medium is channelled lengthwise through the slim housing made of grey cast iron GG20. This cools the motor even with small amounts of water. Moreover, the KTZ, like almost all of the manufacturer’s pumps, is stable in snore operation and dry running.

Top model achieves 216 m
With the similarly designed KTVE in fifth place, many customers chose a pump with a water level switch to save energy costs. Unlike other manufacturers, Tsurumi uses a component without mechanical elements, which in principle promises greater reliability. The electrode switches the pump automatically so that no supervision is necessary. By the way, the LH4110W is listed further down the charts. This pump is a technical superlative in its segment: a single unit is capable of removing 120 tonnes of water per hour from a 216 m deep construction site. Or, alternatively, to manage an even much greater distance or quantity horizontally.

When it comes to dewatering, Tsurumi is the go to brand. In Hall 6, the pump manufacturer presented the new KRDX explosion proof dewatering pump and the new LSC2.75S residue pump. The  company also demonstrated how to get all construction gear on site onto the network: namely, amazingly simply with the Tsurumi Connect-Box.

With it, not only the company’s own pumps can be controlled on the construction site. The solution also works with other devices from other manufacturers. Remote switching, location data, running logs, failure messages and more: lots of things are possible when Tsurumi’s small hardware box is attached to the unit. The tracking data ends up in real time where the user wants it: PC, laptop or mobile phone can be used for remote control and analyse. All is “infinitely” scalable, they said.

The use of the system was demonstrated with the new KRDX submersible pump. It is designed for explosive environments and comes with IECEx and ATEX approval. The series has motor outputs from 3,7 to 7,5 kW. Thanks to the agitator and large pressure outlet, heavy sludge water is no obstacle, even if it contains soils with 33 grain diameter. The pumps can deliver up to 2200 l/min or 17 m head and are scheduled for market launch in early 2023.

In case water is left somewhere, Tsurumi now supplies the new LSC2.75S as a residue dewatering pump with a capacity of 228 l/min. It can absorb water up to 1 mm puddle height. This makes it ideal for taking up water from buildings, containers or roofs. The Tsurumi  team exhibited cutaway models to show how their technology works. A water basin had been set up in which pumps ran in wet live operation: a fine demonstration that went down well with the professional audience.

Tsurumi provides a real proof of performance at stand A6.338: the KRS2-80 pump on display has run for 20,000 hours without maintenance (Figure 1).

The manufacturer set this record quite incidentally. The pump is the company’s own demonstrator for the series. It was put into service in 2001. It was only after 21 years that the first service was carried out – purely as a safety measure in the run-up to the trade fair, so that nothing would go wrong. Unfounded, as it turned out: Only a seal and small parts were replaced. The pump series is one of the most frequently built by the manufacturer and is designed for water containing mud or sand. It moves about 1700 l/min or pushes water up about 16 metres. The water may contain stones with a diameter of up to 30 mm. The pump can be seen in a live wet operation at the stand.

And should it fail, Tsurumi will have a workbench on site as a novelty for visitors to the fair. Pump technicians will use it to demonstrate how to service a pump. Visitors are invited to join in.

And yes: Tsurumi will also be presenting innovations in 2022. Among other pumps, the company will showcase the KRDX. This is a completely new series of safety pumps that are approved according to IECEx and ATEX. The company will also be showing the digital Tsurumi Connect system for seamless monitoring of pumps and other machines, even those from other manufacturers. Operators can use it to determine the location of their machines, read out performance data or define alarm and failure scenarios. If water should leak somewhere, the new LSC2.75S can certainly help: This residual water pump even dries out puddles – proof will be provided at the stand.

Tsurumi, market leader in dewatering pumps, will be lifting the veil on its new safety pumps at bauma 2022 and show visitors how to service a pump properly.

This has never happened before: for the first time, the exhibitor is coming to Bauma with a workbench where visitors can demonstrate their skills. The task is to service a pump, especially in the sensitive areas of hydraulics and electrics. Those who have not yet mastered this can learn it on site at stand A6.338. A valuable lesson, because pump failures can not only be expensive but also end in accidents.

Safety is also the focus of the new product presentation, which the Japanese have saved as a further treat for the fair: For the first time, they are showing the KRDX, a model in their new series of safety pumps that are approved according to IECEx and ATEX. The three-phase submersible heavy-duty pumps are designed for slurry drainage/pumping and have motor outputs from 3.7 to 7.5 kW. They are equipped with an agitator and an outlet of up to 100 mm to pass solids up to 33 mm in size. Tsurumi states a pumping capacity of 2,200 l/min.

Safety, part three: Tsurumi presents its Connect system for seamless monitoring of pumps and other machines, including those from other manufacturers. Via a small box on the unit, the operator can determine the location, read out performance data and set alarm and error scenarios. The aim is to raise safety and efficiency to a new level. The first systems are already in use on the market.

And what else? The manufacturer provides information on many other pump models, including novelties such as the residue dewatering pump LSC2.75S. Some of them are even demonstrated in wet live operation, for which Tsurumi specially sets up a complete basin with piping. Workhorses such as the KTZ and KRS pump series are also represented on the stand, as they form – not without reason – the backbone of dewatering in many construction projects around the globe.

Düsseldorf/Germany, 7.6.2022

At the IFAT booth of exhibitor Tsurumi, it was clear that in addition to pumps as the main elements of the water system, accessories are increasingly coming into focus. Innovations such as the LSC2.75S were demonstrated in wet operation.

A pump here, a submersible aerator there: it’s easy to lose track of everything. It’s not just the systems for submersible aeration that have to run properly to ensure that all parameters are right. With Tsurumi Connect, the manufacturer has presented its system for monitoring and control. All that is needed is a small hardware box that connects to the Internet. Coupled devices – also from other manufacturers – can then be monitored around the clock. In addition, processes can be programmed, locations queried, alarms received and energy consumption called up.

Tsurumi’s retrofit kits for many series are also helpful, including the new TSS-TEG leak sensor. It detects water leaks in the housing. A relay is all that is needed to automatically shut down the system before major damage occurs. The sensor is cleverly integrated into the oil drain plug. It can be installed in no time at all: old screw out, new one in. Float switches were also a topic, because there is another way: Tsurumi’s level sensors are a fail-safe alternative because the electrodes have no mechanics.

In Hall B1, however, the Düsseldorf-based company mainly exhibited its core range of dewatering, residual water and wastewater pumps as well as submersible aerators (Figure 1). In the latter, the TRN-FL is of interest for dissolved air flotation to achieve higher air inputs in the biological clarification stage with smaller bubbles. How well a TRN works was impressively demonstrated in the water basin. Using cutaway models, interested visitors were able to get an idea of how the manufacturer achieves its performance values. For example, with the new LSC2.75S residue dewatering pump, which can collect water down to a residual height of one millimeter.

The coronavirus pandemic is under control, the environment is not. It is time for the upcoming IFAT 2022 exhibition in Munich/Germany. Heavily improved top-of-the-line models in several series will be on display by pump manufacturer Tsurumi at stand B1.444 (Figure 1).

The new LSC2.75S residue dewatering pump is a 36 % more powerful version of the popular LSC1.4S. Now with 750 W of motor output, the shallow suction pump, which is only 37 cm high, moves water with 228 l/min or up to a height of 15 m. From level ground (buildings, containers, etc.) the pump extracts water down to a residual height of 1 mm. It is not necessary to monitor the pumping process. No water runs back when the pump is lifted. Thanks to the narrow housing, the new LSC even fits through a 200 mm pipe.

With the HS3.75SL, the manufacturer is launching a new multipurpose pump for heavy dewatering tasks. Its spiral watercourse is known from the “ultra-hard” concrete pumps. Even chunky lumps can be channelled through without immediately grinding down the internal components. With only 750 W of motor output, it achieves 580 l/min or 11 m delivery head. The pump is the new top model in the HS series, one of Tsurumi’s best-selling pump lines.

The GPN837 has been designed with a lot of attention to detail. It helps removing water with a lot of sand or mud. Compared to its predecessor, the throughput has been doubled to 9,000 l/min. An agitator mixes the pumping medium to make it more flowable. Even massive elements with a grain diameter of 30 mm cannot harm the new top-of-the-range unit. The maximum pumping height is 24 m.

Tsurumi also comes up with a novelty in the submersible aerators. The TRN-FL was developed for use in dissolved air flotation applications (DAF). For this purpose, the manufacturer has improved its basic design with regard to the gas bubble spectrum. Tsurumi achieved a higher air saturation through smaller bubble diameters.

On display at the stand will be numerous pumps from the 500-plus model range, which capacities up to 30 m³/min or 216 m head. The Japanese manufacturer is considered the world’s largest in its field. Technical achievements such as the maintenance-friendly modular design, individually encapsulated conductors and position-independent lubrication stand for long service lives. Cutaway models and live pump operation in the large test basin allow visitors to see how everything works. The options for control and monitoring in the network are manifold, for which a complete system has been set up with “Tsurumi Connect”.
