Micro-pump selection instructions, micro-pumps, micro-circulating water pumps, micro-pump

Now there are a variety of micro-pumps, micro-circulating pump, micro-pump, high-pressure micro-pumps, liquid sampling pump, small pump, self-suction pumps, DC pumps, diaphragm pumps, how to choose their own pumps? Mainly from the following aspects to discuss:
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:
(About 1 ~ 3 kg), mainly used for water circulation, water sampling, lifting, etc., requiring low noise, long life, high self-absorption. Cheng, etc., the optional BSP, CSP series;
2, the flow rate is not high (about 1 to 5 liters / minute), but the pressure is large (about 2 to 11 kg), mainly for spray, booster, high head, you can choose ASP, HSP series;
3, the required volume as small as possible, flow requirements of small (about 0.1 to 3 l / min), optional QSP 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 micro-pump pumping or vacuum, but sometimes there will be liquid water into the pump chamber.
2, requires both micro-pump pumping and pumping.
3, with a micro-pump pumping, but sometimes there is no water pump can pump, in the "dry" state.
Some traditional pumps fear "dry run", "dry run" or even damage the pump. The QSP series of products is essentially a composite function pump, which integrates the function of the vacuum pump and pump, it was called "vacuum pump." Therefore, in the absence of water, it will vacuum, water, when it pumped. Whether pumping state or pumping state, belong to the normal scope of work, it does not matter "dry turn" injury.
4, the main pump with a micro-pump, but do not want to rely on artificial before adding water "diversion" (some pumps in the work before the need to manually add some "diversion", so the pump can pump up the low water, or pump Pumping or even damaged), that is, hope to pump a "self-priming" function. At this time the advantages of PHW series products is that there is no exposure to water, it is vacuum, the formation of vacuum pressure after the pressure up, and then began pumping.
