IMPORTANT INFORMATION - READ ME FIRST! Model Number and Serial Number Record the model number and serial number below for future reference. This is important information when ordering replacement parts or when technical assistance is required. The numbers are found on a label located on the motor adapter. MODEL NUMBER = ____________________________ SERIAL NUMBER = ________________________ IMPORTANT NOTICE U.S.
WARNING: The pump and associated components are heavy. Failure to properly support the pump during lifting and movement could result in serious injury or damage to the pump and components. WARNING: Never run pump at less than minimum flow or with the discharge valve closed. This could lead to pump failure. Installation/Operation Precautions CAUTION: This pump should never be operated without liquid in the casing. It is recommended that run dry protection be used.
Unpacking and Inspection Unpack the pump and examine for any signs of shipping damage. If any damage is detected, save the packaging and notify the carrier immediately. 6. WARNING: Be careful, magnets will try to attract tools. Section I - Assembly Metric Motors: Secure the drive to the motor shaft using bolt, lock washer and flat washer (items 21, 22, 23). Thread the bolt into the end of the motor shaft (while holding the outer drive to prevent it from turning). See figure 6.
Section II – Installation installed ¼” drain in the impeller housing. See the Drain Installation Section for details. Mounting Motor feet should be securely fastened to a solid foundation. Note: Shims are required for the motor feet on ALL 63, 71 and 80 frame motors and 90 frame B5 motors. · For units in a suction lift system, install appropriate piping in the discharge to allow priming of the pump (DB models are not self- priming).
magnet and impeller assembly away from metal chips or particles. Flush Systems CAUTION: Some fluids react with water; use compatible flushing fluid. 1. 1. Turn off the pump. 2. Completely close the suction and discharge valves 3. Connect flushing fluid supply to flush inlet valve. WARNING: The pump must be thoroughly flushed of any hazardous materials and all internal pressure relieved prior to opening the pump. Allow the pump to reach ambient temperatures prior to performing maintenance. 4.
7. Remove the impeller shaft (item 6) from the barrier and check for signs of cracking, chipping, scoring or wear. See figure 15. 8. Remove the barrier (item 7) from the motor adapter (item 11) (make sure the shaft has been removed). If necessary, gently tap on the back side of the barrier with a soft rod (wood, plastic, etc). Inspect the inside and outside of the barrier for signs of rubbing. See figure 16. 9.
5. Install o-ring (item 3) in groove in the barrier. 6. Install impeller shaft (item 6) into barrier by aligning the flats on the shaft with the flats in the barrier. Make sure it is completely seated. See figure 28. Carefully install the impeller/inner drive assembly (items 4A, 4, 5, 5A) by sliding it over the impeller shaft in the barrier. It is normal for the impeller/inner drive to pop up a slight amount due to magnetic forces. See figures 29 and 30. 7. 8. 9.
