FAQs

Troubleshooting Piston and Hydrostatic Pumps and Their Impact on the System and Diesel Engine

Piston and hydrostatic pumps are widely used in industrial hydraulic systems and heavy machinery due to their high efficiency and ability to operate under high pressure. However, if they are faulty, worn out, or improperly adjusted, they can cause issues such as performance loss, excessive load on the engine, unusual leaks, pressure drop, and even engine smoke. Below, we examine 10 of the most common problems in these pumps and recommended solutions to fix them.

-Relief valve stuck or incorrectly adjusted
- Return filter or flow path restricted
- Cylinder/load jammed
- Reduced pump flow causing pressure rise

- Oil overheating
- Internal wear and leakage
- Partial cavitation
- Efficiency loss

- Servo leakage or incorrect zero-setting
- Spool not centered
- Feedback issue
- Swash plate not level (small angle creates displacement)
- Surface wear preventing full neutral position

-Bearing clearance or shaft run-out
- Scratched shaft surface
- Overpressure at seal
- Wrong seal type/material
- Thermal deviation
- Drain/case line blocked -> pressure forces oil past seal

- Poor combustion or weak compression
- Hydraulic load too high: pump not reducing displacement

-Wear between wear plate & cylinder block -> leakage hammering
- Clearance increases = noise increases

- Internal leakage turns power into heat
- Pump not destroking -> excess flow dumped to tank -> heat

- Internal leakage too high
- Displacement not fully achieved

- Bearing clearance
- Misalignment
- Foaming/air intake
- Pressure pulsation

- Contamination or filter restriction
- High viscosity
- Back-pressure increase
