NFS is an authorized dealer of Tsurumi’s proudly best-selling HS-series in NSW. Tsurumi Pumps S3.75SL & HSZ3.75SL model pumps are submersible single-phase portable drainage pumps that come with high volume drainage capability.
Application:
A dewatering pump is used to draw out the water from the Soil. In the mining industry, water is used primarily for mineral processing, dust suppression, slurry transport, flotation and leaching. In order to remove the water from the ore, a dewatering pump is used. On a construction site, the pump helps to create a dry environment so that the work can be carried out without any interruption.
The HS-HSZ Series pump design and performance are best suited to specifically meet the needs of the civil engineering and the construction market. While these pumps are submersible single-phase portable drainage pumps with only 0.75 kW of motor output, they come with max. capacity of 580 l/min and max. head of 10.8 m of drainage capability.

The HS-series is a submersible single-phase portable drainage pump. Though it is a single-phase unit, the pump has the durability equivalent to three-phase drainage pumps, since the wear parts are made of abrasion-resistant materials. The side discharge, spiral design allows smoother passage of the sucked solid matters. The shaft-mounted agitator prevents “Air Lock” that tends to take place on vortex or semi-vortex pumps.

The HSZ-series is a submersible single-phase automatic portable drainage pump. The automatic operation, controlled by a single float switch, reduces consumption and extends operating life.

The main advantage of using a portable dewatering pump is that it can help to speed up the process of construction or mining. It can also reduce the cost of operations as there is no need to use extensive machinery for removing water from the soil. In addition, it can help to protect the environment by reducing the amount of water that is wasted during these processes.
