Troubleshooting, Common Faults & Solutions
No Discharge from Pump
Likely Cause: Incorrect rotation direction, pump unprimed, or blocked delivery line
Action / Part: Verify motor rotation matches nameplate arrow (bi-directional capable), prime pump with liquid, clear blockages in discharge pipework
Loss of Capacity / Reduced Flow
Likely Cause: Worn rotor/stator elements, insufficient NPSH, air entering suction line, or belt drive slipping
Action / Part: Replace rotor (25A) and/or stator (22A), increase suction head, check gland adjustment for air leaks, re-tension drive belts
Pump Stalls at Start-Up
Likely Cause: Product viscosity too high, low voltage, or flexishaft damage
Action / Part: Heat product to reduce viscosity, verify electrical supply voltage, inspect flexishaft (26A) for visible damage or distortion
Excessive Noise and Vibration
Likely Cause: Misaligned coupling, worn bearings, or insecure pump mounting
Action / Part: Check and adjust alignment to motor/gearbox, replace shaft bearings (lubricate with BP LC2 grease), tighten all baseplate mounting bolts
Excessive Gland or Seal Leakage
Likely Cause: Worn drive shaft, damaged mechanical seal, or inadequate gland flush
Action / Part: Replace drive shaft (32A) if gland area worn, install new mechanical seal assembly (10A - M065139G), ensure proper seal flush fluid flow
Motor Overheats / Excessive Power Draw
Likely Cause: Delivery pressure above rated limit, gland overtightened, or pump speed too high
Action / Part: Check for delivery line blockages, loosen packed gland to allow slight drip, reduce pump speed, verify relief valve setting
Rapid Stator Wear / Premature Failure
Likely Cause: Dry running, abrasive product, or product temperature exceeding rating
Action / Part: Install dry-run protection device, ensure pump always primed before starting, cool product or upgrade to temperature-rated stator material, replace with new stator (22A)
Flexishaft Failure or Damage
Likely Cause: Excessive torque, visible damage to protective coating, or shaft distortion
Action / Part: Replace flexishaft assembly (26A - 4.4 kg), check drive clamp bolts (P513) are torqued to 10 Nm, apply Loctite 5910 to shaft assembly per manual
