Pumps, especially miniature pumps, the main parameters are "flow", "pressure" or "head", whether the need for self-absorption and so on.
Selection according to the specific requirements to choose.
First, only need to pump or solution, requires self-priming capability, and the flow and output pressure requirements.
Note: pumping working medium is water, non-oily liquid solution (can not contain solid particles, etc.), self-priming function, you can choose the following pump:
1, the flow requirements (about 4 ~ 20 liters / minute), the pressure is not demanding (about 1 to 3 kg), mainly used for water recycling, water sampling, upgrading, etc., requiring less noise, long life, high self- Cheng, etc., the optional BSP, CSP and other series;
2, low flow requirements (about 1 to 5 liters / minute), but the pressure is large (about 2 to 11 kg), mainly for spray, pressurization, car washing, etc. do not need long hours of work under high pressure or heavy load , You can choose ASP, HSP and other series;
3, for the tea table pumping, spraying, etc., require the volume as small as possible, the flow requirements of small, low noise (about 0.1 to 3 liters / minute), optional PHW, ASP and other series.
Second, you need pumping or gas, value the volume, noise, continuous use and other properties
Description: Requires water and gas dual-use, can be long-term dry turn, do not damage the pump; 24 hours of continuous operation; particularly small size, low noise, but the flow, pressure less demanding.
1, with a mini pump or vacuum pump, but sometimes there will be liquid water into the pump chamber.
2, require micro-pump both pumping and pumping.
3, with a miniature pump, but sometimes there may be no pumping pump, in the "dry turn" state.
Some traditional pumps fear "dry turn", "dry turn" can even damage the pump. The PHW, WKA series of products is essentially a composite function pump, which integrates the functions of vacuum pumps and pumps, some people call it "vacuum pump." So, in the absence of water, it will be evacuated, and when it has water it will pump it. Whether it is pumping or pumping state, belong to the normal work category, it does not matter "dry turn" damage.
4, the main pump with a micro-pump, but do not want to manually increase by pumping water before the "diversion" (some pumps in the work before the need to manually add some "diversion", so that the pump can pump up the water down, or the pump can not pump water or even Damage), that is, I hope the pump has "self-absorption" function. At this point you can PHW, WKA series of strengths is that, in the absence of access to water, it is a vacuum, the formation of a vacuum by air pressure up, and then began pumping.
With the above application, you can choose PHW, WKA series.
Third, there is greater demand on the flow, the medium contains a small amount of oil, solid particles, residues and so on.
Description: to extract the medium,
1, contains soft solid particles less than 31mm in diameter (such as hair, fish feces, sewage sludge, debris, etc.), and can be cut into smaller particles, but the viscosity can not be too large!
2, Allow the working medium contains a small amount of oil (such as a small amount of oil floating on the surface of the sewage), but not all oil!
3, flow requirements, do not need self-priming function of the occasion.
With the above application, you can choose FSP large flow series.
