Screw Star 750-4 Submersible Deep Well Screw Pump 750w Hmax:80m Qmax:2700l/h. 4 BOREHOLE PUMP SCREW STAR 750-4. Sturdy, sand-resistant deep well screw pump made of stainless steel for extremely deep well drilling. With this robust deep well screw pump the pumping of water from extremely deep boreholes, wells or water reservoirs is no problem. It delivers this at high pressure to the point of use.It is suitable for all well diameters from 120mm. This is one of the few real deep well pumps which can cope with sand quantities where the usual impeller pumps fail after a short time! However, the higher the sand content, the higher the wear of the moving parts in contact with dirty water. For this purpose, the pump casing can be opened and the stainless steel screw conveyor and the hard rubber coupling can be easily replaced. This is an EU product with a very long cable and FIXED bs compliant 3 pin converter plug. This item is in the category "Garden & Patio\Ponds & Water Features\Pond & Fountain Pumps".
