What to do if Parker Water Pump drive motor only turns at slow speed?
If the drive motor of your Parker Water Pump only turns at slow speed, consider the following: * **Motor selection:** Use a motor with more horsepower if the current motor is not selected properly. * **Hydraulic blockage:** Check the function of the pump compensator and start the pump at an unloaded system if the pump is hydraulically blocked.
What to do if Parker PV016 Water Pump does not upstroke, sticks at zero displacement?
If your Parker Water Pump does not upstroke and sticks at zero displacement, consider these potential causes: * **Contamination:** The compensator may be blocked due to contamination. Clean the hydraulic fluid and the compensator valve. * **Wiring issue:** The cable to the LVDT or proportional solenoid may be interrupted. Check the wiring and replace the cable if necessary.
What to do if Parker Water Pump drive motor turns, but the pump does not turn?
If the drive motor of your Parker Water Pump turns, but the pump itself does not, check the coupling assembly and correct it, as it might not be mounted correctly.
What to do if Parker Water Pump delivers full flow at low pressure?
If your Parker Water Pump delivers full flow at low pressure, several issues could be the cause. The standard pressure compensator might be set to minimum pressure, so you should adjust the compensator setting to the desired pressure. Alternatively, the orifice in the remote pressure compensator could be blocked, so ensure the orifice Ø 0.8 mm in the control spool is free and open. Other potential causes include: a missing pressure pilot valve connected to port P. R (install a suitable pressure pilot valve and adjust it); an unenergized multiple pressure pilot selector valve (energize the selector valve solenoid); a missing load sensing line (connect the system load sensing port to the compensator); a closed or too small load sensing valve (open the load sensing valve or use a larger valve...
