So that you can keep your system up and running and avoid unplanned downtime. To help, we’ve created a downloadable troubleshooting guide containing more information about each of these issues. If your pump is exhibiting any other issues such as noise problems, heat problems or flow problems, you may need to do some more investigation to address the root cause of your pump problem. In some cases you may find a simple solution is the answer. If your pump is having problems developing sufficient power, following this checklist will help you to pinpoint the problem. Learn to identify other pump problems with our troubleshooting guide. If everything else checks out, uncouple the pump and motor and check to see that the pump shaft is able to turn. Seized bearings, or pump shafts and other internal damage may prevent the pump from operating all together.

Check that the relief valve is adjusted properly for the pump specifications and the application. It is possible that the entire flow could be passing over the relief valve, preventing the pressure from developing. A sheared pump coupling is an obvious cause of failure, however the location of some pumps within hydraulic systems makes this difficult to check so it may go overlooked CHECK TO SEE IF YOUR PUMP COUPLING IS DAMAGED.Ĭheck to ensure the pump to motor coupling is undamaged. If required, overhaul or replace motor.ĥ. If this is the case, correct the misalignment and inspect the motor for damage. In some cases, misalignment can cause binding of the drive shaft, which can prevent the motor from turning. CHECK THAT YOUR DRIVE MOTOR IS OPERATING CORRECTLY.Ĭheck to ensure that your pump drive motor is turning over and is developing the required speed and torque. Check to see that the motor is turning the pump in the right direction and if not - look at your piping.Ĥ.

Sometimes incorrect installation leads to mismatched pipe routings between control valves and motors, which can reverse the direction of flow. Now that we’ve ensured that the directional control is not reversed, it’s time to check that the drive motor itself is turning in the right direction. CHECK THAT YOUR DRIVE MOTOR IS NOT REVERSED which could contribute to poor fluid flow.

Things like restrictions and blockages can impede the flow of fluid to your pump.
