Pumpenregelsystem SYDFEE-2X/028R-PPA12N00-0000-A0A0CX3-002 - Bosch Rexroth R901233254

The job is supplying oil on demand. The variable displacement pump swivels only as far as the machine currently needs, instead of dumping surplus flow across a pressure valve. Size 28 cm³, up to 84 l/min and 280 bar nominal pressure define the working range, and the preload valve is set at 300 bar. Swivel angle control, pressure control and master/slave operation all sit in the on-board electronics of component series 2X.

Key benefits

• Swivel angle and pressure control in the on-board electronics, master/slave operation supported
• 28 cm³ displacement, variable, flow up to 84 l/min
• 280 bar maximum operating pressure as nominal pressure, preload valve at 300 bar
• Analog interface, 24 VDC supply through a 12-pole connector (11 + PE) to EN 175201-804
• FKM seals for HLP hydraulic fluid, clockwise rotation, fitting key shaft
• 23.8 kg weight on an ISO 2-hole mounting flange, without through-drive

Applications

The system is used in power units that have to cover changing demand, for example on injection moulding machines, presses and test rigs. Because the swivel angle follows demand, power loss at part load stays low and the tank runs cooler. Master/slave operation allows several pumps to be combined on one common pressure circuit. Its own supply makes a separate power pack for the control electronics unnecessary.
