AR hydraulic pumps play in your operations—and the challenges that can arise when performance falters. To support your uptime, efficiency, and long-term reliability, we’d like to share concise, actionable insights into the most common operational issues—and how they can be swiftly resolved.
1. Insufficient Pressure or Failure to Build Pressure
Causes may include incorrect motor rotation, blocked suction lines, internal wear, high oil viscosity, or misadjusted safety valves.
Our recommendation: Verify motor direction, inspect and clean the suction pipe and filter, replace worn seals or components, select oil with optimal viscosity, and recalibrate the safety valve pressure.
2. Low Flow or Displacement
This often stems from inadequate motor speed, air ingress at the suction port, low reservoir level, viscous oil, or clogged filters/internal wear.
Our recommendation: Confirm motor speed compliance, tighten all suction-line connections, top up oil to the correct level, clean or replace filters, and assess internal pump wear.
3. Excessive Noise
Typical triggers are poor oil suction, entrained air, leaks in the suction line, damaged internal parts, or misalignment during installation.
Our recommendation: Optimize suction height or tank level, service the filter, secure all connections, inspect and replace compromised components, and verify coaxial alignment during reinstallation.
4. Abnormal Temperature Rise
Contributors include mismatched overflow and pressure-regulating valves, prolonged low-pressure operation, unsuitable oil viscosity, or systemic leakage.
Our recommendation: Reconfigure valve settings, avoid extended low-load operation, use viscosity-appropriate hydraulic oil, and conduct a thorough leak audit.
5. External Leakage
This commonly results from aged or damaged seals, loose fittings, or compromised housing surfaces (e.g., scratches or casting defects).
Our recommendation: Replace worn seals promptly, retorque connections to specification, and repair or replace affected housings as needed.
For rapid troubleshooting, always begin with foundational checks: oil level, viscosity grade, and integrity of all suction-line seals—simple steps that resolve many issues before deeper intervention is required.
