WQ (D)-S All stainless steel precision casting sewage submersible electric pump (threaded)

Product characteristics

1、The oil chamber is double mechanically sealed with fluoroelastomer, and the outer chamber adopts a fluorine rubber single mechanical sealing structure, which effectively reduces the water intake problem of the rotating shaft wear caused by the friction between the sediment and the shaft.
2、The motor adopts vacuum immersion paint to achieve the F class insulation,≤4kW equipped with thermal protector to effectively improve the service life of the pump.
3、Precision casting pump shell with characteristics of light weight, corrosion resistance, energy-saving, good looking appearance, hygiene, environmental protection, etc.
4、Customized mechanical seal with PTFE and high temperature resistant motor (can be used when liquid temperature is≤103℃).

Main Purpose
