PUMP REASSEMBLY Before reassembling the pump, carefully inspect the component parts of the cartridge (stage) assembly, looking for damage, wear or heat distortion. Pay careful attention to spacing direction of components, and location of shims. Refer to Figure 16 for proper facing and parts arrangement. If damage to Stage components is evident, a complete cartridge assembly or individual stage assemblies are available for replacement (See Replacement Parts List). 1. Reassembly should follow the reverse order of the disassembly procedure with special care given to replacement of the rotary seal. 2. Check top and bottom of o-rings for damage. It is recommended that new o-rings be used. 3. Do not use pipe compound of Teflon tape on barrel threads. The o-rings will prevent pump from leaking. 4. After pump is reassembled, tighten the discharge head to a torque of 45-50 ft/lbs. If torque wrench is not available, tighten firmly but avoid distortion or damage to plastic internal parts. 5. After reassembly, apply power momentarily to unit (15 to 30 seconds). The pump and motor should rotate freely or with a light rubbing. 3/4” Pipe Press Carefully Cardboard Washer Protects Seal Seal Face Seal Cavity IL0554 Figure 13 - Remove Mechanical Seal Figure 14 - Press In Seal Figure 15 - If Necessary, Press With Cardboard And Pipe 10 FLINT & WALLING, INC. • 95 North Oak St. • Kendallville, IN 46755 • Troubleshooting Chart Symptom Possible Cause(s) Corrective Action Pump won’t 1. Blown fuse or open circuit breaker 1. Replace fuse or close circuit breaker. See wire size chart for start or run proper break/fuse size at full speed 2. Power supply in OFF position 2. Turn power on 3. Incorrect voltage at motor (check volt3. Low voltage age with motor running) a. Voltage must be within ± 10% of motor rated voltage. Check incoming voltage. Contact power company b. Make certain that voltage of motor matches voltage of power supply. See motor name plate and motor wiring diagrams c. Check wire size from main switch to pump. See wire size chart for correct wire size 4. Loose, broken or incorrect wiring 4. Rewire any incorrect circuits. Tighten connections, replace defective wires 5. Defective motor 5. Replace motor 6. Pump hydraulic components clogged/ 6. Replace worn parts or entire pump. Clean parts if required worn/damaged Pump operates, but delivers little or no water 1. Manual or solenoid valves plumbed into system restricting flow 2. In-line filter restricting flow 3. Low line voltage 4. Inadequate water supply to booster pump 5. Undersized piping 6. Leak on inlet side of system 7. Inadequate, defective or plugged foot valve and/or strainer 8. Worn or defective pump parts or pump. 9. Suction lift too great 10. Pump not primed 11. Incorrect rotation, motor running backwards 1. a Check all valves on pump inlet and discharge sides of system to be sure they are opened properly to allow flow to and from the pump b. Bleed trapped air in pump which keeps water from reaching the pump. (Normally due to closed valve in discharge plumbing) 2. Check all in-line filters to be sure they are not plugged or restricted 3. See low line voltage corrective action (above) 4. Check pressure on inlet side of booster to be sure positive pressure is maintained to the booster pump 5. Replace undersized piping 6. Make sure connections are tight. Repair leaks as necessary 7. Clean, repair or replace as needed 8. Replace worn parts or entire plugged impeller Clean parts if 9. Pump should be operated under flooded suction only 10. Prime pump - Make certain inlet pipe is drawn up tight and pump and pipe are full of water 11. Reverse motor rotation can occur on three phase units. To correct, interchange any two incoming power leads. Excessive 1. Pump not secured to firm foundation 1. Secure properly noise while 2. Piping not supported 2. Make necessary adjustments pump in 3. Restricted inlet line 3. Clean or correct 4. Cavitation (noise like marbles in pump) 4. a. Reduce speed on direct drive b. Increase inlet pipe size c. Too viscous (material being pumped too thick 5. Worn motor bearings 5. Replace bearings or motor Pump leaks 1. Worn mechanical seal (leaks at shaft) 1. Replace shaft (rotary) seal 2. Worn o-ring seals 2. Replace o-ring seals, located inside both ends of the stainless steel shell 11 FLINT & WALLING, INC. • 95 North Oak St. • Kendallville, IN 46755 • 12 FLINT & WALLING, INC. • 95 North Oak St. • Kendallville, IN 46755 • Booster Pump Parts Drawing Figure 16 - Cartridge Assembly Includes Discharge Bearing, Shaft & Coupling Assembly, Diffuser Plate, Impellers, Diffuser Bearings, Diffusers and O-rings NOTE: Illustration shows only two stages.
