The spa pump is technically the heart of your spa or hot tub. Two main parts to a spa pump are the wet end which contains the impeller and a motor to turn the impeller. Spa pumps draw water from suction ports like main drains and skimmers and return the water through the spa jets into your tub. The front of the pump is the location of the intake (or suction) and on the top is where the water leaves the spa pump under pressure. Aquaneo has a wide range of AquaFlo and other brands' spa pumps at affordable prices.
