Tsurumi has unveiled the highest-flow versions of its HS Series pumps with the new HS3.75SL (manual) and the HSZ3.75SL (automatic) submersible, trash pump models.
Designed to handle high volume drainage at low head, the new models pump roughly twice as much water as the high head model HS3.75S for dewatering applications.
The new pumps offer a maximum flow rate of 140 GPM and maximum total dynamic head of 40 ft, with a motor input of just 0.75 kW. Compact and lightweight, the pumps’ wear parts are built from highly durable materials. The shaft incorporates Tsurumi's original agitator to prevent air lock and to stir slurry efficiently.
The difference between the two models is that the HSZ3.75SL contains a simple float switch-equipped automatic sensorto prevent dry-running operation and to reduce power consumption, which makes it appropriate for night-time operations and construction works in dense residential areas.
Glenn Wieczorek, managing director of Tsurumi America, said: “These trash pumps handle debris, sand and solids that come in flooding water with minimum wear and clogging.”
