Tsurumi LH Submersible Dewatering Pumps

The LH series introduces a range of 3-phase contractor pumps designed for achieving exceptionally high head pressures. These pumps are crafted from premium-grade materials, ensuring outstanding durability and performance, even in the most challenging operating environments. The innovative hydraulic architecture includes a dual mechanical seal complemented by an oil lifter, guaranteeing effective seal lubrication under any operational stance.

A standout feature of the LH series is its top discharge design, which cleverly integrates a water and air-cooling conduit. This, in conjunction with a high-efficiency motor, allows for extended operational periods, even in minimal seepage scenarios. The compact base design of these pumps not only facilitates optimal positioning in tight spaces but also simplifies maintenance routines. The ease of part replacement without the necessity for specialised tools enhances the user-friendly aspect of these pumps. Moreover, the high-performance motors are equipped with thermal protection, streamlining the installation process and allowing for a direct connection to the electrical supply.

For specialised applications, the LH series offers the option of IDS (Individually Screened Cable) on most models. This feature is designed to enhance the operational flexibility and safety of the pumps. Interested parties are encouraged to request a quotation to explore this customisation option further.
