| Tsurumi Pump’s high-flow version of its best-selling HS Series pumps, the HSZ3.75SL automatic model pump, is designed to handle high volumes at low head. |
 |
| Tsurumi’s HSE Series pumps are equipped with the company’s industry-leading automatic water level sensor technology. |
These submersible pumps are single-phase portable drainage units with 1 horsepower of motor output, featuring a maximum flow rate of 140 gpm and a maximum total dynamic head of 40 feet. The pump’s high performance makes it suitable for the general needs of the rental market and high-demanding construction applications.
The HSZ Series is equipped with a simple, integrated automatic float switch to prevent running dry and reduce power consumption. It automatically stops running when not needed, making it ideal for round-the-clock.
Tsurumi’s HSE Series pumps are equipped with the company’s industry-leading automatic water level sensor technology. An moisture-sensing e-probe prevents the pump from running dry, minimizing premature damage on wear parts and extending equipment lifespan. Their compact design allows them to operate in areas too small for normal floats.
Operator friendly
As with other HS Series units, these operator-friendly submersible pumps are compact and lightweight, making them easy to transport. Limited maintenance is another strong suit of the pumps, as the models’ wear parts are built with durable materials. In addition, these pumps have a spiral pump casing that effortlessly handles tough substances like mud and soil. The shaft incorporates Tsurumi's original agitator to prevent air lock and stir slurry efficiently.
Tsurumi's original technologies are neatly packed into these pumps. These technologies include an anti-wicking cable, dual inside mechanical seals with silicon carbide faces, and an oil lifter that has been developed through years of research and applications in the field. These design features ensure Tsurumi pumps will perform reliably even in the most demanding jobs, making them ideal for construction projects.
