QDX, QX series submersible pump consists of pump, mechanical seal and motor. Pump is at the bottom part of pump, which is adopted centrifugal impeller. Motor which is single-phase or three-phase is at the upper part of pump. Seal is used where pump and motor combine, which is a kind of double-end mechanical seal, O rings are applied to all static joints. Float switch can be equipped to control pump's starting and stopping automatically according to the water level.
This series pump is small and light, which is widely used in countryside for elevating water from well, irrigation, sprinkling and domestic water supply, and also used in draining off water for fishpond and building site.
The pump can work properly and continuously under following operational conditions:
1. Medium is not corrosive,Sand contents should be max. 0.01% by volume and
granular size should be max. 0.2mm.
2. Medium temperature shouldn't be over 40°C and PH should be 6.5-8.5.
3. The pumps should be operated within rated head.
4. The pumps should be fully submerged into water with depth of less than 3m mad max. the pump should be min. 0.5m over the water bottom and not be insert into sludge.
5.Power frequency should be 50HZ,single phase voltage 220V,three phase voltage 380V,and voltage fluctuation should be 0.9-1.1 times than the rated.
