QW Series Submersible Sewage Pump, 12v dc Submersible Water Pump

QW series submersible sewage pump, 12v dc submersible water pump 

1. What is Credo QW series submersible sewage pump, 12v dc submersible water pump ?

Type QW pump is newly developed on the basis of advanced technology from international. It is used for industry and commerce, the living area, urban sweage treatment plant, wterworks, civil air-defence construction, hospital, hotel and so on. Thwy can also be used in public works, explore, country methane, irrigation, deliver water with impurity. The flow-rte range of the delivery water is 7-10000m3/h, lift range is 7-60m, power range is 0.55-315Kw, caliber range is  φ25-φ700 mm.

2. What are the service conditions?

(1) Medium temperature should not above 60°C, Maximum density is 1.3×103kg/m3.

(2) If the pump without a build-in self-circulation cooling system, its motor should not expose above water more than half.

(3) Deliver medium’s PH value is between 4 and 10.

(4) Solid particle passing capacity is 60% of the inlet diameter, the length of the fiber is 5 times to inlet diameter.

3.What is the structure of QW series submersible sewage pump, 12v dc submersible water pump ?

Type QW Submersible Sewage Pump adopts particular single blade or double blade; advance the ability for get across feculence. Fiber about 5 times as pump caliber can across.Mechanical seal adopt fresh model cemented carbide rot-proof material, and at the same time, we improved on the airproof to the single-ended double-face mechanical seal, let them work in oil chamber for a long period of time.  

The whole structure is compact;, volume is small, little noise and the energy saving result was apparent. The machine needn’t pump room .It can work just dinning into water, so reduce project cost.

The float switch can control sutomatically, do not need specially-assigned person. It's very convenient. According to need, we can equip automatic coupler installation system. So people needn't get into the drainge ditch. Can be used in all range of lift, and it won't overload. there are two diffrent install way, fixed type automatic installation system and movable type automatic installation system.
