What to do if my Parker PV016 Water Pump drive motor does not turn?
- M
  Matthew WilsonAug 22, 2025
  If the drive motor of your Parker Water Pump isn't turning, it could be due to a few reasons. First, check the motor connections and the electrical power supply to ensure they are correctly connected and functioning. It's possible that one of the three phases has failed. If the motor connections and power supply are fine, the pump may be mechanically blocked, in which case you should send the pump to the factory for service.

Why Parker PV016 drive motor turns, but pump does not turn?
- S
  stephengallowayAug 25, 2025
  If the drive motor of your Parker Water Pump is turning but the pump itself isn't, the coupling might not be mounted correctly. Check the coupling assembly and correct it.

What to do if Parker PV016 drive motor turns and pump turns, but there is no output?
- A
  Angel AndersonAug 26, 2025
  If the drive motor and pump of your Parker Water Pump are both turning, but there's no output, consider these possibilities: Ensure the direction of motor rotation is correct by changing it if necessary. Check that the fluid reservoir is filled to the required level and increase the suction pipe length if needed. Inspect the suction line for blockages and open any valves in the line, ensuring they have electrical indicators. Also, check the suction filter. Seal the suction line to prevent air from entering. Unload the pressure port and system before starting, and bleed air from the pressure line if the pressure line/system cannot bleed air out.

How to fix unstable compensator on Parker PV016?
- T
  thomasamyAug 28, 2025
  To address an unstable compensator in your Parker Water Pump, consider these steps: First, clean the hydraulic system and compensator valve, as the compensator spool might be sticking due to hydraulic fluid contamination. Next, adjust the compensator differential pressure to the required setting, as it may have changed (becoming too low or too high). Ensure the correct pilot orifice and pressure pilot valve are selected as recommended. If dealing with a dynamic critical system, such as a pressure compensator combined with a pressure reducing valve, use a remote pressure compensator instead of a standard one, and install an orifice in the load sensing line remote from the compensator, as close as possible to the load sensing valve.

What to do if Parker PV016 does not compensate?
- D
  David RodriguezAug 30, 2025
  If your Parker Water Pump isn't compensating, check these potential issues: Ensure there is an orifice Ø 0.8 mm in the load sensing line to compensator code MFC. Verify that a pressure pilot valve is connected to the compensator and that the valve opens as required. Confirm that the load sensing line is connected downstream (actuator side) of the load sensing valve. Also, ensure that the pump outlet pressure is at least 15 bar, as the bias spring in the pump cannot be compressed otherwise.

Why Parker PV016 Water Pump drive motor only turns at slow speed?
- S
  Sharon HernandezSep 1, 2025
  If the drive motor of your Parker Water Pump only turns at slow speed, it could be due to improper motor selection or a hydraulically blocked pump. Start the pump at an unloaded system and consider using a motor with more horsepower. Also, check the function of the pump compensator and start the pump at an unloaded system.

What to do if Parker PV016 Water Pump does not upstroke?
- H
  harveydonnaSep 3, 2025
  If your Parker Water Pump does not upstroke and sticks at zero displacement, it could be due to a blocked compensator or an interrupted cable. Clean the hydraulic fluid and compensator valve, as the compensator might be blocked due to contamination. Check the wiring to the LVDT or proportional solenoid to ensure the cable is intact; replace it if necessary.

What to do if Parker Water Pump does not build up pressure, but delivers full flow at low pressure?
- N
  nicole14Sep 5, 2025
  If your Parker Water Pump delivers full flow at low pressure but doesn't build up pressure, here's what you can check: * **Pressure compensator setting:** Adjust the compensator setting to the desired pressure if it's set to minimum. * **Pressure pilot valve:** Install a suitable pressure pilot valve and adjust it to the desired setting if none is connected. * **Multiple pressure pilot selector valve:** Energize the selector valve solenoid if the pump works in stand-by because the valve is not energized. * **Differential pressure:** Check the differential pressure adjustment and correct it if it's too low.

What to do if Parker PV016 delivers no output flow?
- A
  Allison NguyenSep 9, 2025
  If your Parker Water Pump delivers no output flow, here are a couple of things to check: * **Motor connections:** Verify the motor connections and check the electrical power supply, as the motor might not be connected correctly or one of the three phases may have failed. * **Mechanical blockage:** If the pump is mechanically blocked, send it to the factory for service.

  pattytownsendSep 12, 2025
  If your Parker Water Pump does not compensate, here are a couple of things to check: * **Pressure pilot valve:** Connect a pressure pilot valve to the compensator, ensuring the valve opens as required, if no valve is connected or if the valve is blocked. * **Pump outlet pressure:** Ensure the pump outlet pressure is at least 15 bar, as the bias spring in the pump cannot be compressed otherwise.
