Pumpenregelsystem SYDFEE-2X/028R-PRA12KD3-0000-A0A0CX2 - Bosch Rexroth R901307311

A power unit should deliver only as much oil as the axis currently needs. The SYDFEE-2X/028R pump control system regulates swivel angle and pressure directly at the variable pump: 28 cm3 displacement, up to 84 l/min flow and 280 bar operating pressure, run by the on-board electronics of component series 2X.

Key benefits

• Swivel angle and pressure control in one unit, so flow follows demand instead of spilling across a relief valve.
• 84 l/min from 28 cm3 displacement covers mid-sized power units.
• Preload valve at 250 bar, below the 280 bar nominal rating, secures the suction circuit.
• Master and slave operation allows several pumps to work together on one system.
• Through-drive included, a second pump can be flanged on without an extra motor.
• FKM seals and ISO 2-hole flange with geared shaft (R), clockwise rotation.

Applications

Control systems of this kind work in power units for presses, test rigs and plastics machinery, where holding phases and rapid traverse call for very different oil volumes. Its own supply and the analog interface on the 12-pole connector link the unit to the machine controller without additional electronics. At 25.3 kg the assembly is mounted on a bracket or directly on the motor flange.
