The Advantage of Pumps
High metering accuracy and repeatability
Manual control via hand wheel with built-in-
precision measuring scale or
alternative mechanical rod control, for mounting pneumatic or hydraulic control cylinders
Operating
pressure up to 250bar
Low suction
pressure, even when pumping highly viscosity materials
Very little pulsation of flow
Quite
operation
Optimum volumetric available
It
can be used all parts together with Rexoroth A2VK pumps.

MA Manual Control
By turning the hand wheel, the pump
swivel body and thus the displacement or output flow is
infinitely varied within the range Qo to Qmax via a
self-locking threaded spindle.
