How does a pool pump work?

The job of your pump is to basically draw water through the filtration system so that the pool water is kept clean and is properly circulated. The pump is driven by an electric motor directly attached to the pump impeller. As the electric motor turns, it causes the impeller to turn, which then forces water to flow through the pump.

The water flows into the hair/lint pot inlet (ie: in built ‘strainer’ that catches leaves and other large debris before they get sucked into the pump and clog the impeller), and through the basket assembly. The flow then enters the centre of the pump housing, goes through the impeller, into the diffuser, and out the pump discharge port and onwards to the pool filter where the water is filtered before it is sanitised and/or heated.

After being filtered, the water is then pumped back to the pool.

The things they take into consideration include:

• How big is the pool and what is the volume of water?
• How long do you need to circulate the water?
• Does the pool have ancillary equipment such as an in-floor cleaning system, pressure pool cleaners or water features?
• What is the distance from pool to pump and what are it’s pipework characteristics?
• Is a suction cleaner used?

There are certainly continued growth of multi-speed and variable speed pumps, with pool owners attracted to the energy savings and low noise emissions they generate. The improved filtration systems and specialised valves such as the FlowVis flow valve maximises energy efficiency while simultaneously ensuring sufficient flow and pool turnover.
