Why is my OilGear PVM-011 making excessive noise?
- K
  Kimberly MeltonAug 7, 2025
  Excessive noise in your OilGear Water Pump can stem from several issues. It might be due to incorrect start/stop procedures under load, so verify the pump's operational procedure. Check the fluid level in the reservoir and supercharge to address potential cavitation. Inspect the system for leaks that could allow air to enter. Ensure the fluid isn't too cold or viscous; check its temperature and type. Examine the suction line for obstructions, excessive length, small diameter, or too many bends. Also, confirm the pump is rotating in the correct direction.

Why is my OilGear Water Pump excessively heating up?
- D
  Duane JohnsonAug 12, 2025
  If your OilGear Water Pump is overheating, several factors could be responsible. First, ensure the pump isn't operating above its rated or peak pressure by verifying its limitations. Check the fluid level in the reservoir and supercharge. Inspect the system for air leaks. A worn piston pump could also be the cause, so inspect and replace components if necessary. Ensure there's sufficient cooling and that coolers aren't clogged. Use the highest drain port to maintain proper case fluid level. If the OP2 is too large or missing, causing excessive case drain, decrease its size. Finally, inspect the sequence spool; replace it and the valve plate if necessary.

  If your OilGear Water Pump isn't delivering enough volume, start by verifying that the load sense differential pressure is less than the pump control setting. Inspect the PC control cartridge for damage or obstructions; clean or replace it as needed. Adjust the stroke limiter screw (70) counter-clockwise. Check for obstructions in the suction circuit and verify supercharge. Ensure the drive motor speed is sufficient. Finally, inspect the cylinder barrel (38) and port plate (43) for wear or grooves, and replace components if necessary.

What to do if OilGear PVM-011 Water Pump operation is irregular?
- K
  Kevin MitchellAug 20, 2025
  Irregular operation of your OilGear Water Pump can be caused by several factors. Check the system flow control valve/orifice for fluctuating load sense differential pressure. Inspect the control piston (19), sequence valve (54), or PC control cartridge (55) for faults and replace if necessary. Verify the fluid level and supercharge. Inspect the system for air leaks. If low viscosity fluid is used, increase the size of OP2. If the remote PC setting is close to the pump PC setting, increase the pump PC setting. Inspect for worn axial piston pump components. Finally, inspect the output circuit components (cylinder, motors, valves) and replace if faulty.

How to troubleshoot unresponsive control on OilGear PVM-011 Water Pump?
- C
  Christopher MckeeAug 25, 2025
  If your OilGear Water Pump control is unresponsive, start by inspecting the stability orifice (OP2) for any blockage and clean it if contaminated. Also, inspect the PC control cartridge (55) for damage and replace if necessary.

What causes excessive pressure in OilGear PVM-011 Water Pump?
- B
  Brian MyersAug 29, 2025
  Excessive pressure in your OilGear Water Pump can arise from faulty output circuit components, so check the relief valves. Also, inspect the PC control cartridge (55) for faulty operation and replace components if needed. Lastly, inspect the saddle bearing (30) for wear or breakage and replace components if necessary.

Why is my OilGear Water Pump losing pressure?
- D
  David MillerSep 1, 2025
  A loss of pressure in your OilGear Water Pump can be due to a worn piston pump. Inspect the components and replace them as necessary.
