Troubleshooting, Common Faults & Solutions
No Discharge from Pump
Likely Cause: Incorrect rotation direction, pump unprimed, or drive train breakage
Action / Part: Verify motor rotation matches nameplate, prime pump with liquid, inspect flexishaft (26A) and drive clamp assembly (27A, 27B) for damage
Loss of Capacity / Reduced Flow
Likely Cause: Worn rotor/stator elements, insufficient NPSH, air entering supply line, or pump speed below rated
Action / Part: Replace rotor (25A) and/or stator (22A), increase suction head, check all pipe joints for air leaks, verify pump speed settings
Pump Stalls at Start-Up
Likely Cause: Product viscosity exceeds rated level, low voltage supply, or discharge blockage
Action / Part: Heat product to reduce viscosity, verify electrical supply voltage is correct, clear discharge line obstructions, check relief valve operation
Excessive Noise and Vibration
Likely Cause: Coupling misalignment, insecure pump mounting, or shaft bearing failure
Action / Part: Check alignment to motor/gearbox, tighten all baseplate mounting bolts, inspect and replace shaft bearings if worn (lubricate with BP LC2 grease)
Excessive Gland or Seal Leakage
Likely Cause: Worn drive shaft, damaged mechanical seal, or inadequate gland flushing
Action / Part: Replace drive shaft (32A) if gland area shows wear grooves, install new mechanical seal assembly (10A), ensure proper seal flush fluid flow
Motor Overheats / Excessive Power Consumption
Likely Cause: Delivery pressure exceeds rated limit, gland overtightened, pump speed too high, or coupling misalignment
Action / Part: Check for delivery line blockages, loosen packed gland to allow slight drip (2-3 drops/minute), reduce pump speed, verify alignment
Rapid Stator Wear / Premature Failure
Likely Cause: Dry running, abrasive product, product temperature exceeding rating, or stator turning in housing
Action / Part: Install dry-run protection device, ensure pump always primed before starting, cool product or upgrade to temperature-rated stator, tighten stator tie bars (95A) to correct torque
Flexishaft Damage / Failure
Likely Cause: Excessive vibration, improper drive clamp torque, or protective coating damage
Action / Part: Replace flexishaft assembly (26A), ensure drive clamp bolts (P513) torqued to 17 Nm in correct sequence, verify drive clamp pins (27B) properly installed
