The pump is the heart of the filtration, but on its own it won’t save the pool. It must match the pool volume, the filter, the pipe length, the resistance of the fittings and the required filtration time. For reputable pump manufacturers, watch efficiency, noise level, service and the performance curve.
Ask the quote to include why the company chose a specific model and what filtration schedule it recommends for normal operation, heat waves, holidays and after heavy bathing load.
The pump’s location in the plant room affects noise just as much as the motor’s own output – proximity to a bedroom or a neighbouring plot is worth considering already when designing the plant room. A frequency converter also helps extend the pump’s lifespan by reducing start-up surges. On an older pool, check that the new pump matches the existing pipework, not just the filter.
When replacing an old pump with a new, more efficient one, check that it matches the voltage and protection in the plant room – a more powerful motor may require rewiring. It’s also worth comparing noise levels during night-time operation, if the pump also runs outside daytime hours for longer filtration on hot days.
