The Viper 56 Frame Spa Pump is to be had for dual speed motors only. It has a 5HP rating with 230 volts and has a Viper wet end designed specifically for 56-Frame motors. Its two double-shielded ball bearings have moisture-resistant grease for quieter operation and long life. The Viper has a dual speed motor with four sets of insulated windings for increased efficiency, and a 2-1/2″inch intake and discharge. Its large 8 diameter wet end is designed for increased volume capacity.Center vs. Side Discharge Pumps Swimming pool and spa pumps are classified, in part, in step with the orientation of their discharge openings. Center discharge pumps have an opening positioned in the center of the wet end, at the same time as side discharge pumps have an opening positioned at the side of the wet end. Water is propelled through the openings and flows out through the jets in your spa. Side discharge pumps are up to 60% more efficient for pumping out high volumes of water than center discharge pumps.What the frame size on a spa pump mean? The frame size on a spa pump is the physical size of the spa pump motor. The frame is the piece that mounts the wet end to the motor. The frame size is positioned at the motor’s ID plate, frequently marked with an F for frame size. The thru-bolt spacing may be an indicator of frame size. A 48 frame motor has bolts spaced lower than 4 inches apart, and the 56 frame motor has bolts with spacing more than 4 inches apart.
