The heavy-duty motor is 110 volts, self-priming. The self priming pump features a hair and lint strainer. Use only #20 silica sand. Available in two sizes: 1/2 HP Pump Sand Filter (for pools up to 5,500 gallons) or 3/4 Pump Sand Filter (for pools up to 15,000 gallons). Both filters include an adapter for Intex pools and Sand N Sun Easy Set Pools.
