How to choose the most suitable water pump
1. The listing head in the nameplate or specifications of the water pump is rated head, the corresponding flow is rated flow (the efficient of the pump is the largest based on this ratio), when the rotational speed of the water pump is fixed, the head of the pump is not constant, it decreases with the increase of water flow of the pump, the shaft power of the pump and the current of the motor increases with the increase of water flow of the pump, if the actual flow exceeds 1.2 times of the rated flow, the motor will be burned easily.
2. The flow is the amount of the liquid delivered by the pump in the unit time(volume or weight), the head is the energy increment of the unit weight liquid pumped by the pump from the pump inlet (the pump inlet flange) to the pump outlet, it is the Pumping liquid column height, it is called meter, the suitable head of the pump is very important to the service life of the pump.
3. Different pump, different application, usually the actual head can reach 0.9-1.05 times of the rated head, the actual flow can reach 0.7-1.2 times of the rated flow.
