Troubleshooting, Common Faults & Solutions
Pump hose burst (leakage)
Likely Cause: Excessive discharge pressure or chemical attack.
Action / Part: Check system pressure and hose compatibility. Replace Hose.
Low capacity (flow)
Likely Cause: Suction line restricted or hose worn (loss of restitution).
Action / Part: Clear suction or replace Hose.
Pump overheating
Likely Cause: Low lubricant level or incorrect shim adjustment.
Action / Part: Refill Hose Lubricant (2899920100) or adjust shims.
Excessive noise/knocking
Likely Cause: Cavitation (starved suction) or worn bearings.
Action / Part: Increase suction head or replace Bearings (28-B142460).
Short hose life
Likely Cause: Pump speed too high for application or high temperature.
Action / Part: Reduce speed or check process temperature limits.
