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.

Operating Pressure Range-inlet side
Open circuit : Prefill pressure 1~3 bar absolute at suction port S
Closed circuit : Sum of combined pressure at A and B ≤ 250 bar (315 bar for short period),
fit leakage at port T
 
Operating Pressure Range-outlet side
Pressure at port A or B
Nominal pressure ---------------------------- Pn = 250 bar
Peak pressure -------------------------------- Pmax =315 bar

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.
