Pump Failure Troubleshooting

Pump Failure

Troubleshoot pump failure in sprayers, HTP systems and water pumps.

What this guide solves

Pump failure can involve seals, valves, dry running, clogging, motor/engine drive or wrong fluid handling.

Compatibility rule

A spare part is recommended only when exact model, size, rating, part family or supplier evidence supports it. Category-fit suggestions remain marked for confirmation.

Buying workflow

Find the machine model, identify the failed part, compare evidence, check replacement interval, then order or ask support when any detail is unclear.

Compatibility decision table

Step What to Check Why It Matters
Stop safely Switch off, depressurise or disconnect battery Avoid injury
Diagnose basics Fuel, spark, air, pressure, oil, chain/blade/nozzle Most faults are simple
