QJ(D)Y Multi-stage submersible electric pump for well

Product characteristics

1、Motor optimization: supporting power is greatly improved, with stronger power, lower temperature rise and greater water volume;
2、Impeller upgrade: increased flow, improved electric pump efficiency, better energy efficiency and more efficient water intake;
3、Class B capacitance, Class F insulation, with intelligent thermal induction protection and longer service life;
4、Double bearing structure can withstand more axial force. The pump shaft is upgraded to 304 stainless steel which is more anti-corrosion and wear-resistant;
5、The impeller and fluid conductor are made of high temperature resistant material to ensure the reliable operation of the pump for a long time and make it a longer life;
6．Pin disassembly structure and plug type power wiring, which is more convenient for disassembly, repair, and maintenance.

Main Purpose

This series of electric pumps use multi-stage impeller structure, with high elevation and wide applications. It is widely used in farmland drainage and irrigation, garden sprinkler irrigation, underground water lifting, water delivery of water power and other occasions.
