The pump is practically the heart of the entire spa or pool system in which it is connected to. Moreover, find out what is the total dynamic head of the system otherwise known as the friction loss brought about by the fittings, equipment, and piping.

In choosing the pump most suited for your pool, you would need to know the actual volume of the pool in terms in the amount of water it can hold and the required flow rate in relation to turnover time.. Close estimates would do just fine, although make sure that you do not under estimate. This line connects to the pump where water passes through a strainer basket going to the impeller. The impeller is a rotating pump connected to the electric motor shaft that generates centrifugal force through spinning.com

The purpose of an electric motor-powered pump is to create hydraulic flow and pressure required in making water circulate through a plumbing system of a pool or spa and other related equipment. Water is first drawn from the pool via a hose known as the influent line.

You would have to use some basic geometry to estimate the volume of the pool. This is the force that brings out water through the effluent line moving towards another equipment which is usually a pool filter.

On exactly how the pool pumps circulate the water, the process actually involves several steps.

Normally, you can buy pool pumps in either Watts or "horsepower" (Hp). Centrifugal force is essentially the outward movement of the water brought as a result by the rotation of the impellers. All pools and spas contain pumps which is one of the most important pieces of equipment in the circulation system regardless of the type or size of the pool. To make it simple, set your measurements in tenths of feet in order for your calculations to be in simple decimal form. The higher the pump's horsepower is, the more amount of water it can circulate - which also means higher performance. A pump's performance is commonly measured in liters per minute (L/min). The dimensions do not have to be absolutely accurate especially if you do not know the actual specs. Find out the general dimensions of the pool. You should also check the flow rate of the model you are purchasing because two different pumps with similar wattage or horsepower may actually produce varying volume per minute rate.
