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.
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, stainless steel motor shaft, longer wear resistance life.
Oil immersionmotor, using foodgrade mechanical oil, fast dissipation
mechanical oil, good cooling effect, do not pollute the water source.
