Swimming Pool Pump
Swimming Pool pump is the heart of the pool system.
The swimming pool pump is attached to the electric motor which drives the impeller inside pump casing generating the vacuum to suck in the pool water. The water is sucked through various drains to the pump strainer, casing and finally to the center of the impeller. As the impeller spins, centrifugal force throws the water through the slot in the impeller and into the diffuser at high pressure and then out through the pump discharge port. The pressurized water will flows through the piping, filter, equipment and back to the pool through pool inlets.
Always buy a swimming pool pump made by well-respected, major international manufacturers such Hayward, Pentair, Sta-Rite and Speck – well respected, large, international market leaders. Other less recognizable pump brands are most likely imports with dubious quality.
The motors used on US made pool pumps are mostly made by Regal Beloit (AO Smith sold off the business), Century or Emerson. The motors are drip proof motor with opening at the bottom of the motor to allow for ventilation by the internal motor fan. The opening creates potential problem for the motor as compared to totally enclosed fan cooling (TEFC) motor with no opening and ventilation by the eternal motor fan.
