             Pulsatron Suction and Discharge Valve - Replacement Procedure

                ƒ  Flush pump to clean any chemical from the liquid end.

                ƒ  Unplug pump, release system pressure, and disconnect tubing or piping.
                ƒ  Unscrew the suction and discharge valve cartridges and return to Belanger.
                   Also remove o-rings internal to the pump head.
                ƒ  Install new suction and discharge cartridges with stamped letter reading from
                   top to bottom, and the arrow pointing in the direction of flow. Hand tighten
                   ONLY; DO NOT use wrenches or pliers. Over tightening can cause the
                   distortion of the seats.
                ƒ  Reconnect tubing or piping and reinstall the pump.
                ƒ  Prime Metering Pump and check to assure the valves are leak-free.

             Questions to be asked prior to returning a Pulsatron
             Solenoid Metering Pump

                •   Was the Pump difficult to prime or lose prime during normal operation? Seal
                    distortion could cause these issues.

                •   Has the volume of chemical being dispensed dropped off significantly?
                •   If the valve ball is not seating properly the volume of chemical will reduce during operation.
                •   Leakage at suction or discharge valves? Distortion of ball seat could cause the chemical to leak through the
                    check valves.
