Pumpenregelsystem SYDFED-2X/028R-PPA12N00-0000-A0ANVXX - Bosch Rexroth R901434789

A power unit should deliver only as much oil as the machine actually needs. This SYDFED pump control system with a variable displacement pump of 28 cm³ per revolution controls swivel angle and pressure through its own digital electronics and supplies up to 84 l/min at 280 bar operating pressure.

Benefits

• Controlled variable pump of 28 cm³ per revolution and up to 84 l/min delivers only the flow actually demanded.
• 280 bar nominal pressure with swivel angle control and pressure control in one unit.
• Digital on-board electronics on a 24 VDC supply, connected by analogue signal or fieldbus.
• Master and slave operation allows several pumps to work into one circuit.
• Clockwise rotation, fitting key shaft and ISO 2-hole flange, supplied without through-drive.
• FKM seals, rated for HLP hydraulic fluid.

Applications

Intended for hydraulic power units on machine tools, presses and test benches where pressure and delivery follow the load. Electrical connection is a 12-pole (11 + PE) connector to EN 175201-804. The system weighs 20.5 kg and is mounted to the drive motor through the ISO 2-hole flange.
