What is a Clutch Pump?

For apparatuses that function through the use of fluids, it is often imperative that there is a pump within the system that is capable of creating displacement and flow. With the use of a hydraulic pump, mechanical energy may be converted into fluid power energy with ease. Through positive displacement operations, the outlet flow of fluid is sealed from the inlet flow. With a hydraulic clutch, hydraulic components act to actuate the clutch of a system when a pedal or lever is pushed in. The use of a hydraulic clutch pump is quite similar, ensuring the functionality of various systems.

Within a particular apparatus featuring a clutch pump, the master cylinder of the assembly will serve as a hydraulic pump. With its use, fluid may be directed to the slave cylinders that are placed down the line. When used for operating a clutch, a slave cylinder actuates the clutch fork, resulting in the clutch friction plate being disengaged from the flywheel. In order to return the assembly to a resting state, a return spring is used.

 A hydraulic clutch pump assembly may be compared to a cable clutch, their results being similar while their processes differ. With a cable clutch, the clutch is pulled in and out through its attachment to a pedal and lever. Within a hydraulic clutch assembly, meanwhile, a cylinder placed at the pedal allows for fluid to be fed to a cylinder which actuates the lever for adjusting the clutch as required.

 Clutch pumps are generally used in lieu of power take-off pumps in various applications such as wreckers and bucket trucks. They are also a requirement for any truck that lacks a power take-off aperture on their transmission. For their placement, the clutch pump is placed within the engine compartment, secured through the use of a mounting kit. Due to their method of operation and operating characteristics, it is important that there is enough space for the pump under the hood of an automobile.

 Depending on one’s particular needs, various clutch pump types such as the spring clutch pump may be used. Generally, one should consider the horsepower requirements of the particular application and any limitations of engine belts. Typically, clutch pumps find common use in hydraulic applications that exhibit flows upwards of 15 GPM.

Although their operations are fairly simple, such components can run into issues from time to time, such as the build-up of air. When air begins to build up in a clutch system, it can be useful to know how it can be removed for optimal operations. Generally, air is pushed out of the system by directing it through the fluid line and into the bleeder valve situated on the slave cylinder. With the use of a tube, cleanliness can be upheld as the tube is connected to the bleeder valve nipple. This will allow for one to guarantee that air is removed from the system while controlling the flow of escaping materials.
