Product  Introduction 

   4ST series well submersible pump is a new energy-saving aquatic products, widely used for farmland irrigation, industrial and mining enterprises drainage

and people in the plateau mountain water, and diving motor together into diving underwater work.
   It has simple operation, small volume, light weight, convenient installation and maintenance, safe and reliable operation, high efficiency and energy saving.


  4/5ST Stainless Steel Deep Well Pump

The tool for lifting water from deep wells is suitable for groundwater in deep wells, and can also be used for water lifting projects such as rivers, reservoirs, and canals for farmland irrigation.

It can also be used as water for humans and animals in plateau and mountainous areas, and can also be used for drainage in cities, factories, railways, mines, and construction sites.

Flow range: 1-230M3/H Head range: 1045 meters

Product  Advantages

  Submersible motor adopts high temperature resistant cream lead wire, stainless steel outlet strong wear resistance, built-in heat protector can product motor, sand resistant floating plastic POM impeller, wear resistant, pressure resistant graded impeller can absorb water for many times, high flow and high elevation. 

  Using decompression oil capsules,  the dive depth can reach 80 meters,
designed for low voltage start, and the electric pump can be set at 160V-230V Normal work,   plastic POM motor shaft, longer wear resistance life.  Oil immersion motor, using food grade mechanical oil, fast heat dissipation, good cooling effect, do not pollute the water source.
