Tsurumi increase flow capacity of best seller

Tsurumi pumps

New HS3.75SL and HSZ3.75SL models pump around twice as much water as high-head version

TSURUMI have unveiled the highest-flow versions of their best-selling single-phase HS Series pumps: the HS3.75SL (manual) and HSZ3.75SL (automatic).

Designed to handle high-volume drainage at low head, these new, submersible models pump approximately twice as much water as the high-head model HS3.75S, thereby saving time and money in dewatering applications.


‘Our new HS3.75SL and HSZ3.75SL models are ideal for applications where customers need to dewater faster so they can get on to the job site quicker,’ said Glenn Wieczorek, managing director of Tsurumi America.

Designed to handle debris, sand and solids with minimum wear and clogging, the new trash pumps offer a maximum flow rate of 140 gal/min and maximum total dynamic head of 40ft, with a motor input of just 0.75kW.

Compact and lightweight, the operator friendly pumps are easy to transport and require little maintenance, as their wear parts are built from highly durable materials.

Moreover, the shaft incorporates Tsurumi’s original agitator to prevent air locks, as occasionally seen in vortex pumps and semi-vortex pumps, and to stir slurry efficiently.

The difference between the two models is that the HSZ3.75SL contains a simple float switch-equipped automatic sensor to prevent dry-running operation and to reduce power consumption. It automatically stops the pump from running when not needed.

‘At Tsurumi, 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,’ said Mr Wieczorek.

Also packed into the compact pumps are Tsurumi’s original technologies, such as an anti-wicking cable, dual internal mechanical seals with silicon carbide facing and an Oil Lifter, developed through years of research and applications in the field.
