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.
