The hydraulic pumps drives gearboxes consist of a gear drive inside a bell housing that connects to a gasoline or diesel engine. The opposite side contains one or more standard 2- or 4-bolt flanges for mounting hydraulic pumps. This configuration provides several benefits. For one, two 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 two to four pumps simultaneously. This not only offers design flexibility, but can boost system efficiency as well.
We have two pump drives, three pumps drives and four pumps drives for the buyers` option. Customized requirements could be satisfied.
