Troubleshooting, Common Faults & Solutions
Pump hose failure
Likely Cause: Chemical attack, fatigue, or improper shimming.
Action / Part: Check chemical compatibility and replace Hose (2806520X00).
Low flow rate
Likely Cause: Worn hose, restricted suction, or viscosity too high.
Action / Part: Replace Hose or check suction line and fluid viscosity.
Excessive noise or vibration
Likely Cause: Cavitation, loose mounting, or worn bearings.
Action / Part: Check suction conditions (NPSHa) and inspect bearings.
Pump overheating
Likely Cause: Lack of lubrication or excessive discharge pressure.
Action / Part: Check lubricant level (2899920100) and system pressure.
Short hose life
Likely Cause: Incorrect shimming, high speed, or high temperature.
Action / Part: Adjust shims (2806523000) and verify operating parameters.
