Swimming pool pumps are typically end suction centrifugal pumps or self-priming pumps designed to circulate the entire pool contents within 8 hours. Typical features of such pumps are low running speeds to ensure longevity due to hours run, basket strainers fitted on pump inlet to ensure any debris such as leaves or other small objects do not enter the pump. Chemicals are typically added to water via a dosing pot which directly feeds the pump ensure steady dilution within the pool.
Due to swimming pool pumps operating a large proportion of each day it is important they are specified correctly and operate at the most efficient point on their curve. Devices such as variable speed drives can be added to reduce the speed of the pump ensuring it operates more efficiently. At 80% of a pumps duty point, a pump requires only 50% of the energy required at 100% running speed. VSD is likely to become mandatory for swimming pool pumps in the near future as they currently consume the most energy within a house after an air conditioning system.
