Stainless Steel Borehole Pump
Our stainless steel borehole pumps of 4XR and 4XRS series are water pumps that are directly connected with motors. They are water lifting equipment that can be submerged into the water to work. LEO borehole pumps are widely used in the following areas:
Water supply from deep wells
Irrigation
Water supply for mining and construction sites
Water supply for human being and livestock in plateaus or mountain areas

Guidelines to Performance Curves
Tolerances to ISO 9906, Annex A
All curves have been made with 50Hz and 2850r/min
Measurements have been made with airless water at a temperature of 20℃ and kinematic viscosity of 1mm2/s. A motor with higher rated output is required when liquids to be pumped has a higher density than that of water.
Curves include losses (loss due to non-return valve).
4XR Series Stainless Steel Borehole Pump
Borehole pump of this series has double seal and stainless steel casing, and can be quickly installed. It is of abrasion-resistant construction. The wear plate is connected with the floating impeller, ensuring optimum resistance to abrasion. Additionaly, this water pump is equipped with a non-return valve to prevent any water hammer.
