How to choose the correct pool pump

All pool pumps have different flow rates, correlating filters and specific applications.

Sand filters are fussy and like water flowing through them slowly. They have a minimum and maximum flow rate.

Cartridge filters only have a maximum flow rate because there is no back-washing. There is no minimum flow rate required. Cartridges filters can handle a much higher flow rate compared to sand filters. 

Energy Efficient Pumps are becoming more popular and dramatically reduce pool operating costs. They are available in different output models from 1 HP and up to 2 HP, which allows a wide range of water flow rates.
