QJ,QJD series stainless steel multistage deep well submersible pumps are composed of motors and multistage impellers. The pumps are composed of impellers, guide blades, pump bodies, inlet and outlet joints, as well as pump shafts, axle sleeves and guide bearings. The motor adopts double end face mechanical seal, and the seal ring is "O" rubber for static seal.
Pump shell adopts 201 seamless stainless-steel tube, 100% copper motor, high polymer plastic impeller and has the advantages of simple structure, high efficiency, low noise, safe and reliable operation, easy installation and maintenance.
QJ,QJD series stainless steel multi-stage deep well submersible pumps are widely used in deep Wells, hot Wells and ocean extraction, and also in rivers, reservoirs and canals, etc. They are mainly used for farmland irrigation and water for people and livestock in highland mountains, and also for water supply and drainage in cities, factories, railways, mines and construction sites.
QJ, QJD series multi-stage deep well submersible pump can be divided into tens or hundreds of meters underground to extract raw water. It can also be used as a fountain pump, more operations in the municipal square fountain, etc. The pump has multipurpose, small volume, light weight, obvious effect, cheap price etc.
1. The electric pump motor adopts the F insulation class and can withstand temperature up to 155℃. The motor is filled with special oil for machinery.
2. The main parts of the unit are made of stainless steel. The upper end cover of the motor, the pump head and the inlet joint are available in copper and nickel-plated iron.
3, the unit wear resistance and rust, beautiful appearance, easy to install.
4, the hydraulic performance of the electric pump is excellent. Pump can be used in full head.
QJ, QJD pump is especially suitable for groundwater extraction in factories, schools and rural areas. It is the most ideal equipment for groundwater extraction in geological and hydrological engineering, industry, civil use and drainage and irrigation.
