A7VK Axial piston variable pump , Metering pump for polyurethane components
Hydraulic fluids
The pump is approved for pumping and metering polyurethane
components (polyol and isocynate). For other hydraulic
fluids, consult with Bosch Rexroth Service.
MA control
Turning the handwheel turns a threaded spindle which steplessly adjusts the pump’s rotary group, and thus the flow in the range from Vg min to Vg max. A manual locking device, which is fitted as standard equipment, prevents unintentional adjustment. The precision adjustment display is integrated in the handwheel.
