QH Submersible Pump

QH Submersible Pump Detail:

QH Submersible Pump Performance:

Head range:up to 500m3/h 

 Flow range:up to 300m

QH Submersible Pump Application:

QH stainless steel submersible pumps suitable for offshore platform fire-fighting, thermal dissipation, seawater desalinization, seawater lifting, coastal square fountain, mari-culture and attemperation as ground source heat pump in coastal area, it also can lift underground drinking water and mineral water, etc.
 

QH Submersible Pump material:

QH series stainless steel submersible pump has several kinds of material, for seawater and strongly corrosive medium; austenitic stainless steel 316; 316L; or tin bronze, etc. If the medium corrosive in moderately, could use austenitic stainless steel 304, etc.

QH Submersible Pump using condition:

2.  Motor cavity must be filled with water.
3.  The first stage impeller of the pump should be more than 2mm below the moving water surface, pump unit should be less than 70m below the static water level.
4.  The distance from the motor bottom to well bottom must be more than 3m.
5.  Water temperature should be no more than 20°C.
6. Sand content of the water ( by mass) should be no more than 0.01%.
7.  PH value of water 6.5-8.5.
8.  Hydrogen sulfide content of the water should be no more than 1.5mg/L.
9. Chloride ion content of the water should be no more than 400mg/L
10. Water yield of water source should ensure the requirements of pump continuous working.
