Pumpenregelsystem SYDFE1-2X/028R-PRA12KD3-0000-C0X0XXX - Bosch Rexroth R900780051

As soon as several variable pumps feed the same circuit, the division of roles decides stability. This pump control system runs as master or as slave, provides up to 84 l/min from a 28 cm³ displacement and regulates up to 280 bar maximum operating pressure.

Benefits

• Master and slave operation, several pumps feed one circuit in an ordered way
• Swivel angle and pressure control, 280 bar nominal pressure
• 28 cm³ variable displacement, up to 84 l/min maximum flow
• Analog communication, 24 VDC supply, own supply inside the control loop
• Geared shaft (R) with clockwise rotation, ISO 2-hole mounting flange, through-drive fitted
• FKM seals for HLP hydraulic fluid, 22 kg weight, component series 2X

Applications

Grouping several pumps is typical for large presses and test plants with widely varying demand. In slave mode the unit follows the master set point instead of working against it. The through-drive accepts a further pump on the same drive shaft.
