4DGS-A/D 4 Inch High Speed Deep Well Pump

4DGS-A/D 4 Inch High Speed Deep Well Pump

Product Features:

  1. Permanent magnet DC brushless synchronous motor: The efficiency is increased by 15% – 20%, saving energy consumption.
  2. The whole 304 stainless steel rotor shaft avoids the risk of shaft breakage.
  3. Stainless steel outlet/connector/oil cylinder, with better corrosion resistance.
  4. Japanese NSK bearing, longer working life.
  5. Two deep groove ball bearings are used at the upper end, and two angular contact bearings are used at the lower end, which can withstand greater radial force and axial force.
  6. Two silicon carbide-impregnated graphite mechanical seal of Italian brand, longer service life and deeper submerging depth.
  7. 180°C high temperature resistant copper wire, insulation class F.
  8. Cold rolled 600 silicon steel sheet stator and rotor.
  9. The magnet is made of 40SH NdFeB (neodymium iron boron), with a temperature resistance of 150°C.
  10. S/S pump shaft, impellers adopt whole-stage floating wear-resistant and sand-resistant structure.
  11. The whole pump is small volume and strong power, saving the pump installation cost into the well.
