In our families, install circulation pumps is becoming more and more popular. But most friends don’t know how to choose one suitable pump for them, today I will introduce some knowledge about this.

Different manufacturers have different models, and there is no standard name of them. However, we can find some same technical data to meet our requirements. I suggest according to the following suggestions:

1. Pump Head

The pump head is very important which is essentially decide the circulating water pressure. The water resistance will rise during water circling in the pipe, and the distance which also affect the resistance, the circulation pump needs to overcome these resistance to achieve the normal circulation of water, so an important parameter of the circulation pump is pump head.

2. Instant flow

Hot water can be circulated through pipes. One of the most important reference data is the instantaneous flow rate. The greater the instantaneous flow, the more heat it emits in principle.

3. Power

In fact, the power of the circulating pump essentially determines pump head of the circulating pump and the flow of the circulating pump.

4. Diameter of inlet and outlet pipes

There are many types of circulating pumps according to their size and the diameter of their inlet and outlet pipes. These will be selected according to your needs, especially same and easier connect to the installed pipes.
