The long shaft deep well fire pump is a vertical pump composed of single or multiple centrifugal or mixed flow impellers and diversion shells, water pipes, drive shafts, pump bases, motors and other components. The pump base and the motor are located on the upper part of the wellhead (or pool), and the motor power is transmitted to the impeller shaft through the drive shaft concentric with the pumping pipe, which drives the impeller to generate flow and head.
Long shaft deep well pump is a kind of widely used pumping and drainage equipment, suitable for power plants, steel plants, mining, chemical, fire protection, water plants, agricultural irrigation and other industries.
Working Conditions
(1) The temperature is not higher than 40℃
(2) The solid content is not more than 0.01% (by weight).
(3) The PH value is 6.5 to 8.5.
(4) The hydrogen sulfide content is not more than 1.5 mg/L and doesn’t contain any oils.
1. The motor adopts pure copper coil, having better conductivity and higher operating efficiency
2. Adopting stainless steel shaft, high wear-resistant performance, increasing the service life of the pump
3 .Using stainless steel impeller, stronger corrosion resistance
4.Using high quality flange to enhance pressure resistant performance
