serpentine belt driven hydraulic pump in stock

Hydraulic pumps convert mechanical energy into fluid power energy. All hydraulic pumps are positive displacement which means the outlet flow is sealed from the inlet flow. A small amount of fluid is designed to leak internally to lubricate and cool the internal components of the pump. The only function of the pump is to produce flow in a system. Bailey International, LLC provides a wide range of pumps and accessories including clutch pumps, dump, gear, jaw couplers, mounting brackets, pistons, PTO, vane and two stage pumps.

The clutch pump in most hydraulic applications is driven by a belt on a integral pulley, driven by either a gas or diesel engine. When there is no power to the clutch the pump does not engage. But when power is applied to the clutch the pump will engage and provide pressure to the hydraulic system.

Muncie clutch pumps provide hydraulic power at the flip of a switch. Clutch pumps can be used in situations where a PTO aperture is unavailable or difficult to access. Although normally belt driven, clutch pumps may also be shaft driven from the engine crankshaft.

PF4 series pumps are more compact and are driven via a serpentine belt. (Some kits utilize the OEM pulley and belt, while others use an add-on crankshaft pulley.)

There is a lot to consider when planning the optimal way to power a vocational truck application, such as cost, available space, system power requirements, among many other variables. While it seems the vast majority of hydraulically powered work truck applications today utilize a power take-off as its primary power source, a common alternative is a hydraulic clutch pump.

A hydraulic clutch pump is a belt-driven pump that can be used instead of a power take-off for some applications, such as wreckers and bucket trucks, and is necessary on trucks without a power take-off aperture on the transmission.

A clutch pump is mounted to the engine compartment of the truck utilizing a mounting kit to secure in place. It is important to make sure there is enough space under the hood to accommodate the appropriately sized pump. The pump is belt-driven from the crankshaft pulley through an electric clutch, similar to what may be found on an automobile air conditioner compressor. Most applications will use a poly-V serpentine belt or two V-belts to drive the pump.

When considering a clutch pump, one critical aspect is to understand the horsepower requirements of your application versus the limitations of the engine belts. Most engine type belts can only drive somewhere between 7–18 horsepower which prohibits the use of large displacement pumps and may not provide enough displacement to effectively power the application at hand. With that said, clutch pumps remain a popular option for hydraulic applications requiring flows up to 15 GPM.

Muncie Power currently has clutch pump options and mounting kits available for most popular truck chassis including current models of Chevy/GMC, Dodge/Ram, Ford, International, and Freightliner.
