Increased pump flow rates

Tsurumi increases flow capacity of its HS Series single-phase pump line.


Tsurumi has unveiled the highest-flow versions the HS3.75SL manual and HSZ3.75SL automatic pumps. Designed to handle high volume drainage at low head, these new, submersible models pump roughly twice as much water as the high-head model HS3.75S.

“Our new HS3.75SL and HSZ3.75SL models are ideal for applications where customers need to dewater faster so they can get onto the job site quicker, such as construction and utility jobs, and in disaster remediation, when time is crucial,” say  Glenn Wieczorek, managing director of Tsurumi America. “These trash pumps handle debris, sand and solids that come in flooding water with minimum wear and clogging, which makes them a great support in such events.” 

The new pumps offer a maximum flow rate of 140 gpm and maximum total dynamic head of 40 feet, with a motor input of just 0.75 kW. Compact and lightweight, they are easy to transport and operator friendly. Low maintenance is another strength, as the pumps’ wear parts are built from highly durable materials. The shaft incorporates Tsurumi's original agitator to prevent air lock that is occasionally seen in vortex and semi-vortex pumps, and to stir the solids with water so it can pump efficiently. 

“We are always looking for ways to offer the best solutions to meet our customers’ needs. The HS3.75SL and HSZ3.75SL pumps were designed with that in mind,” Wieczorek says. “And, of course, they have Tsurumi’s high standards of quality and reliability. You can’t find anything similar in terms of performance and design out in the marketplace.” 

Built compactly into these pumps are Tsurumi's original technologies, such as an anti-wicking cable, dual internal mechanical seals with silicon carbide face and an Oil Lifter, developed through years of research and applications in the field.
