Tesk Pumps: VSP 401 Series Borehole Pumps

The 4-inch VSP pump series undergoes meticulous design and manufacturing to achieve optimal resistance against sand and impurities, ensuring prolonged lifespan and trouble-free operations. Its Floating Impeller design provides exceptional durability against wear and tear caused by sand and other contaminants. The Discharge Head and Motor adapter, crafted from precision-cast stainless steel, offer maximum corrosion resistance, strength, and a rigid coupling to the motor. Additionally, the integrated Non-Return Valve in the discharge outlet serves to support the water column’s weight, safeguarding against water hammer and protecting impellers and diffusers.
