Small submersible pump selection

Small submersible pump selection
First, only need to pump or solution, requires self-priming capability, and the flow and output pressure requirements.
Note: The pumping of the working medium is water, non-oily liquid solution (can not contain solid particles, etc.), self-priming function, you can choose the following pumps:
1, the flow requirements of the larger (about 4 to 20 liters / minute), the pressure is not high, mainly for water circulation, water sampling, upgrading, requiring low noise, long life, high self-absorption process, the optional WQ Submersible sewage pumps, QDX small submersible pumps, and other series;
2, the flow rate is not high (about 1 to 5 l / min), but the pressure is mainly used for spray, booster, high head, you can choose QY submersible pump, QX high-lift pump, QJ deep well pump series ;
3, the requirements of the volume as small as possible, small flow requirements, optional QDX micro submersible pumps and other series.
Second, the need for pumping or gas, value the volume, noise, continuous use and other properties
24 hours continuous operation; volume is particularly small, low noise, but the flow, the pressure is not high requirements. The water can be dry, long-term dry, do not damage the pump;
1, with a small submersible pump pumping or vacuum, but sometimes there will be liquid water into the pump chamber.
2, requires a small pump can pump air pumping.
3, with a small pump pumping, but sometimes there is no water pump can pump, in the "dry" state.
