The heart of the pool system is the water pump.
In a typical pump system, an electric motor spins an impeller inside the pump housing. The impeller creates a suction, drawing water from the drains, vacuum points, skimmers or gutter drains and then pushing it through the filter and back out to the return inlets. The pump has a strainer basket which catches leaves and other large debris that could clog the internal mechanisms of the pump. Pumps are usually made of different varieties of plastics, metals, cast iron and even bronze, and they have different pumping capacities (measured in either kw or hp), which are calculated in accordance with the volume of pool water and the turnaround time (i.e. the time it takes for all the water in the pool to be re-circulated through the filtration system). This calculation will depend on factors such as weather conditions (temperature in particular) and bather load (i.e. number of people that will use the pool).
