Many people use water pumps maybe ignore many details and there are also many misunderstandings. Here we analyze and resolve the common misunderstandings of the use of these pumps.

1. High head pump for low head pumping

In order to prevent motor overload, it is generally required that the pump's actual pumping head should not be less than 60% of the nominal head. When the high head is used for pumping water with too low head, the motor is easily overloaded and generates heat. In severe cases,the motor may be damaged.

2. Large diameter pump with small Water pipe pumping

Many people think Large diameter pump with small Water pipe pumping can increase the actual head. In fact, after the pipe diameter is reduced, the actual head of the pump will not increase, will decrease, resulting in a drop in the pump efficiency.

3. The outlet is above the normal water level in the outlet basin

If the outlet is above the normal water level in the outlet basin, the pump head is increased but the flow is reduced.If due to topographical conditions, the water outlet must be higher than the water level of the outlet basin, then elbows and short tubes should be installed at the outlet to reduce the height of the outlet.
