Descriere produs
The Pump Drives (Hydraulic pump Drives) is a gearbox allowing the connection between a prime mover (internal combustion engine or electric motor for example) and 1 or more hydraulic pumps. Usually it is used on both stationary and mobile application where mechanical power must be converted into hydraulic power for the purpose of operating travel functions and services.
The hydraulic pumps drives gearboxes consist of a gear drive inside a CHINAMFG housing that connects to a gasoline or diesel engine. The opposite side contains 1 or more standard 2- or 4-bolt flanges for mounting hydraulic pumps. This configuration provides several benefits. For one, 2 or more identical pumps can be connected to provide nearly identical hydraulic output flow from each. Or different sized pumps can be used provide output flow proportional to the displacement of each pump.These gearboxes not only saves space and weight but also eliminates the number of components and reduces assembly time for the whole machinery. Our modular pump drives could allow driving 2 to 4 pumps simultaneously. This not only offers design flexibility, but can boost system efficiency as well.
