How to Assemble Aqua Flo Water Pumps

If you own a swimming pool, hot tub, spa or whirlpool, the water pump filters the water to keep it clean. During the filtration process, the water circulates from the main drain, pushes through the filter and returns to the port of the pool. The Aqua-Flo brand features various models of water pumps such as the Circ-Master, Flo-Master HP/CP and the Flo-Master XP series. Although installing an Aqua-Flo water pump is not a difficult task, you first have to assemble certain parts to ensure proper alignment of the pump components.

Instructions

  1. Replace the Volute Seal

    • 1

      Press the seal -- ceramic part of the pump -- of the rubber boot in the center chamber until it hits the bottom.

    • 2

      Apply a little water to the beaded area on the outer rim of the rubber boot.

    • 3

      Press the two pieces evenly into the chamber.

    Align the Volute with the Motor

    • 4

      Center the motor shaft inside the seal of the motor and make sure the motor does not touch the seal when positioning the volute.

    • 5

      Hold the volute in place and slightly tighten the four thru-bolts into the volute legs.

    • 6

      Make any adjustments to center the motor shaft and the seal before tightening the bolts to secure the volute in place.

    Replace the Impeller

    • 7

      Remove all foreign matter from the ceramic mating and carbon surfaces of the seal before replacing the impeller. Clean the components using alcohol wipes or low lint wipes that contain isopropyl alcohol.

    • 8

      Place the rotary member of the seal portion over the impeller sleeve and twist it until it makes contact with the base of the sleeve. Apply water to the sleeve to seal the sleeve and be sure the carbon surface is facing forward.

    • 9

      Hold the motor shaft securely at the rear of the motor and hand tighten the impeller by turning it clockwise onto the motor shaft. Be sure the ceramic part of the seal in the volute makes contact with the carbon portion of the seal.

    • 10

      Position the floating wear ring over the impeller hub and secure it in place.

    Replace the Suction Cover

    • 11

      Examine the O-ring to make sure there is no damage to the part and replace it if necessary.

    • 12

      Position the O-ring on the suction cover. Lubricate the ring with a non-water petroleum jelly or soluble grease.

    • 13

      Position the suction cover in place and secure it to the volute using a Phillips head screwdriver to screw it in place. Position the cover evenly by when tightening the screws by alternating from one side to the other.
