If you’ve got a hydraulic pump leak in your equipment, you should consider getting the problem fixed sooner rather than later. Every hydraulic system employs a pump that creates the high pressures that move the hydraulic motors and cylinders attached to the equipment. Since each system has a pump, every system has the possibility of a hydraulic pump leak.
Hydraulic pump leaks are possible and will eventually happen to every hydraulic pump, but there are a few things you can do to help extend the life of the pump in your system. Hydraulic pump leaks are caused by fluid bypassing the pump shaft and leaking out. A hydraulic pump is a two-part machine with the two parts connected by a shaft. First, there is the actual fluid pump which is most often a positive displacement style pump. Then, there is a motor that drives the pump, either a gas or diesel motor or in smaller applications, an electric motor.
In any pump there is always the possibility of leakage and the design of the pump will dictate where the most likely leak point is. Many times the shaft that connects the pump to the motor will have a fluid seal around it to keep the hydraulic fluid contained to the pump end of the equipment. Other types of pumps may have a fluid seal around a piston, or around the pump chambers to keep fluid it where it’s supposed to go.
These pump seals lead a difficult life as they are subject to extreme pressures inside the hydraulic system. Depending on the application fluid pressures can range from hundreds of PSI to thousands. Depending on the pump design, the seal could see huge pressure spikes followed by a vacuum to draw fluid from the hydraulic reservoir into the pump. These seals also see extreme temperature swings and have to hold back hydraulic oil which can be abrasive.
Minimizing the abrasiveness of your hydraulic fluid is the best way to prevent a hydraulic pump leak in your system. Hydraulic fluid is designed to withstand the temperatures and pressures of your equipment and keep things lubricated and cooled. As it does its job it will pick up metal wear particles that become suspended in the fluid. These tiny metal particles add abrasive properties to your hydraulic fluid and can slowly wear away at the internals of the components. The first things to wear out will always be your seals, most often in the pump causing a leak there.
Keep your filters clean and regularly changing your hydraulic fluid is the best way to prevent leaks in your system, even a hydraulic pump leak. Check your equipment’s owner’s manual or contact the nearest dealer for more information on regular maintenance you can perform on your equipment.
Since you’ve already got a fluid leak, it’s important to fix that problem as well. The reality is that most of your hydraulic pump is probably in good condition, it’s just a seal that is worn out. The most cost effective thing to do is often to simply repair that seal rather than replacing the entire pump. BlueDevil Hydraulic Stop Leak is the most effective way to seal your hydraulic pump leak quickly and easily!

A pump on my gravley is leaking a little it takes 20-50 motor oil in it , is ok to use the product??
The BlueDevil Hydraulic Stop Leak is safe and compatible to use on your Gravely, however, it is only intended for rubber seals/gaskets. Because of the functionality of the pump, it wouldn’t allow the product to stay in the pump long enough to help seal it. Replacing the pump may be your best option.
