If you use a hydraulic pump that is having problems, you may have to have it repaired by a professional. If you do not, problems will only get worse and then you may have to have the hydraulic pump rebuilt or replaced. Before anything like this happens, below are two problems you may have with your pump, so you will know what you should do.
Making Loud Noises
If you are hearing loud noises coming from your hydraulic pump while it is running this could be due to many things. In most cases, however, it is due to aeration. This occurs if any air gets into the hydraulic fluid, which can contaminate the fluid. Once this contamination takes place the hydraulic pump will start making loud noises when it is compressing and decompressing.
Check the intake lines on the hydraulic pump as they may be cracked or deteriorated. Also check all fittings and clamps to ensure they are tight. If you see any intake lines that look old or deteriorating replace them with new ones or tighten anything that is loose. This will take care of your problem.
If you do not do anything, the aeration will cause the hydraulic fluid to deteriorate, which then causes less lubrication to moving parts inside the pump. This will lead to seals burning and overheating. If the motor overheats it will need to be replaced. In a case like this a professional may be able to rebuild the hydraulic pump.
Leaking Inside the Pump
If you notice leaking inside the hydraulic pump this is a problem, you may be able to take care of yourself. For example, a valve or seal may need to be tightened or replaced.
If you still see fluid leaking, there could be a break in the fluid line. If this is the case, this is a much more serious problem. This is because a line break will cause the pressure to drop inside the hydraulic pump, and when this happens the entire pump will break down. If you do not contact a professional at this point it can lead to expensive repairs or a rebuild.
Contact a hydraulic pump contractor in your area if you think you are having any kind of problems. They will know if it would be best to rebuild the hydraulic pump. Doing so is much less expensive than purchasing a new pump, and it will allow your pump to last much longer for you.
