5.5 Hp / 4 kw / 14 stage / 4 Inch Three Phase Bore Pumps

 

This pump is suitable for a bore casing larger than 100mm in diameter as the pump diameter including the cable guard is 100mm. You would need to allow a few millimeters on either side of the pump for water to flow past the pump. It can also be used with a 5" or 6 " 150mm bore casing. If it is to be used in a 5 " or 6 " bore casing, it is recommended that you shroud the pump. This helps keep the motor cool. This pump is best suited to bores varying from 46m deep to 72 m deep. Designed for domestic clean water use. This pump has radial or semi-axial impellers. The impellers and the diffusers are in plastic material (noryl), whereas the bearings are in ceramic / rubber lubricated by the water circulation. The check valve is incorporated in the delivery body with threaded outlet. The coupling pump motor is made to conform with NEMA regulations, it has ISO9000-2000 management certification and CCC, CE safety certification.

The stainless steel deep well submersible pump is a superior product, made with the latest technology and materials from the 21st Century.  The main part of the deep well submersible pump is made of ture 304 stainless steel and copper alloy. I have noticed some pump companies advertising that they use 304 stainless steel, when in fact they use Grade 304L, the low carbon version of 304. The impeller is specially designed and restructured.  The inducer casing is modified by polycarbonate to strengthen its wear resistance.

The inducer in each level requires an independent silicone rubber shaft bearing.  The motor consists of the liquid-immersed structure which requires a radial thrust bearing with a strong support force and is mechanically leak proof.
