At present, a miniature water pump according to the matching motor power asked to distinguish between, the motor three-phase power requirements, the voltage is 380 volts; single-phase motor, the voltage is 220 volts, so when the choose and buy should pay attention to. General household lighting power is 220 volts, 220 volt power supply of micro pump is more economical.

The flow of the pump must be based on the needs of the user courtyard planting, breeding, processing and life and so on the need of water, water conditions and use of the situation to choose. If the water source is relatively abundant, the water pump is determined mainly according to the maximum water demand.

Select the pump head selected on the lift pump nameplate should be greater than the actual water level. Under normal circumstances, should be more than 20% of the actual lift. Similarly, the pump suction head (allowing suction height) should be greater than the actual suction Shui Yangcheng, otherwise, the pump will be difficult to draw water to.

Water is well, but also to consider the hole diameter and the maximum diameter of the pump body. If the WQ series miniature submersible pump, it should pay attention to the maximum diameter of the pump should be less than the diameter of the hole, otherwise it can not be installed into the well to go. If to choose WXB series micro pump, you should consider good and well assembly form (direct counterpart pump, wife to match the pipeline pumping, and hand pressure pump with the pump and so on) a feasibility plan.
