Variable-Displacement Pump
The KVAA variable-displacement pump is designed to run power attachments on commercial vehicles, such as cranes, winches, grapples, booms, and slews.
Compared to fixed-displacement pumps, the axial-piston unit eliminates the need to divert
excess hydraulic flow to the oil reservoir.
This reduces fuel consumption, permits
a smaller oil cooler, and gives operators
finer control of attachments. The pump
is suited for demanding applications that
call for smooth, efficient, precise, and
faster work operations. Three nominal
displacement sizes are 55, 80, and
107 cm3/rev. Nominal pressure rating is
300 bar, with peak pressure to 350 bar.
Control options are constant pressure
with load-sensing, or stepless electric-proportional control. The self-priming
pump is for open-circuit operation, and it complies with relevant European and
SAE standards.
