Features of A8VO Hydraulic Pump

Variable double pump is equipped with two axial conical plunger rotating components with inclined axis design for hydrostatic transmission in an open circuit
The flow rate is proportional to the input speed and displacement, and it changes steplessly from qv max to qv min(0)
The pump is suitable for mounting directly on the flywheel housing of a diesel engine
The auxiliary pump and the two oil circuits share one suction port
Powerful control program, which can realize different control and adjustment functions
Independent power controller
Built-in auxiliary pump with pressure relief valve, optional additional pressure relief valve
A variety of power output devices can be used to install axial piston and gear pumps
Outstanding power/weight ratio
Long service life– Long service life
