When buying a micro-pump, you must choose the type you need according to different situations.
At present, the micro-pumps are divided according to the power requirements of the matching motors. There are three-phase power motors required, with a voltage of 380 volts. There are single-phase power motors that require a voltage of 220 volts. The general household lighting power supply is 220 volts. It is economical and convenient to purchase a miniature pump with a 220 volt power supply. The flow rate of the water pump must be selected according to the water demand, water source conditions and usage of the user's yard planting, breeding, processing and living. If the water supply is sufficient, the model specification of the pump is mainly determined based on the maximum water demand. The head of the selected pump nameplate when selecting the pump head should be greater than the actual water delivery height. Under normal circumstances, it should be about 20% larger than the actual headroom. Similarly, the pump suction head (allowed to suck up the vacuum height) should also be greater than the actual suction head, otherwise the pump is difficult to pump water.
The source of the water is well water, but also consider the well bore diameter and the maximum diameter of the pump body. If the WQ series micro submersible pump is selected, it should be noted that the maximum outside diameter of the pump should be less than the inside diameter of the well bore, otherwise it cannot be installed in the well. If you want to choose WXB series micro-pumps, you should consider the feasibility of the well assembly method (direct port pumping, pumping the original matching pipe, pumping with the hand pump, etc.).
