Tsurumi Pump Offers Solutions for Small Spaces

Chandler, Ind.-based KM Specialty Pumps and Systems saw an opportunity to drive sales in the power plant industry when they had a recent uptick in rental in that space.  So, the company purchased two Tsurumi KRS822 pumps to add to its rental fleet, knowing the pumps could operate in small spaces with high-volume performance, which would help to meet demand for pumps within the power plant industry.

The KRS series provides high-volume performance with an extended pump life. The extension of the pump life is the result of reduced impeller tip speed, which makes the wear and tear of the pump less severe over time and even extends the parts wear life by at least two to three times. This is made possible by a 4-pole, 1800 RPM/6-pole, 1200 RPM motor.

The physical size of the pump is what initially interested KM Specialty Pumps and Systems in purchasing the two KRS units, as it is easy to place the pump through a hatch at the opening of a well that rivers run through. The company’s customers have had great success in using these pumps to clean river intakes at power plants throughout the Midwest.

Derrick Carr, power generation and rental field sales and service specialist for KM Specialty Pumps and Systems, said that the company chose the two pumps for its size and durability, and that several of its customers use the same pumps for work on river intakes.

“The small footprint of these KRS pumps makes them ideal for this application due to size constraints of the lid opening,” Carr said. “This pump takes in shells, mud, sticks, rocks, sand and more. The pump’s capacity is also crucial and has proven to be very successful for our customers who need to pump river intakes.”

The Tsurumi pumps are great for long-term jobs and have been rented out the majority of the time that KS Specialty Pumps and Systems has owned them. With no nuisance calls about these pumps, the company plans to invest in more of them in the future.

For power plants, it is necessary to have this application done on a quarterly basis to ensure proper flow through river intakes to the power generation facility. Carr notes that the pumps durable iron construction enables them to endure tough applications adequately.

“The suction plate on this pump is also close to the floor, which helps remove materials closer to the floor and therefore does a more efficient job,” said Carr.

The pumps have helped resolve issues for many KS Specialty Pumps and Systems customers. Tsurumi provides a variety of sizes in its KRS series, making this particular type of pump ideal for a multitude of different applications. A notable component of not only the KRS series, but all Tsurumi pumps is the anti-wicking block, which prevents water incursion because of capillary wicking should the power cable be damaged, or the end submerged. Its pumps also include dual inside mechanical seals with silicon carbide faces that provide longer operational life of any seal available. The pumps also feature a patented oil lifter that provides lubrication to the seal faces – down to 1/3 of normal oil level – and extends seal life by 10 times while using no additional power.
