Pumpenregelsystem SYDFEE-2X/028R-PPA12N00-0000-A0A0VX1 - Bosch Rexroth R901490875

Fixed pumps with throttle control turn every unused litre into heat. The SYDFEE-2X/028R-PPA12N00-0000-A0A0VX1 instead adjusts the swivel angle of its 28 cm³ pump electronically, supplying only the flow the process calls for at up to 280 bar.

Benefits

• Variable pump of 28 cm³ per revolution, flow to 84 l/min, operating pressure to 280 bar.
• Swivel angle plus pressure control through the on-board electronics, analog command interface, 24 VDC supply.
• 200 bar preload valve, the lowest setting in this series, suited to fast destroking on load release.
• Fitting key shaft with ISO 2-hole mounting flange, clockwise rotation, no through-drive.
• 23.8 kg weight, FKM seals, HLP hydraulic fluid, 12-pole connector (11 + PE) to EN 175201-804.

Application

The control system belongs in power units for machine tools, presses as well as test rigs whose oil demand swings across the cycle. Because swivel angle follows demand, tank temperature plus noise stay lower than in throttled operation. The analog interface allows the unit to run as master or slave inside a group.
