Pumpenregelsystem SYDFE1-2X/028R-PPA12N00-0000-A0X0XX1 - Bosch Rexroth R901015485

Not every machine has a separate pilot circuit a variable pump can be tied into. The PPA12N00-0000-A0X0XX1 version of the SYDFE1 supplies itself, holds the pilot pressure with a 200 bar preload valve and comes with a fitting key shaft and no through-drive.

Benefits

• Own pilot oil supply with a 200 bar preload valve, no extra pilot circuit has to be built into the plant.
• 28 cm³ displacement, up to 84 l/min, the flow tracks machine demand through the swivel angle.
• 280 bar maximum operating pressure with an analog setpoint at 24 VDC.
• Fitting key shaft with ISO 2-hole flange, the coupling sits on a cylindrical shaft with a key and the drive is defined clockwise.
• No through-drive, 23.8 kg weight, a compact build for power units with a single pump.

Applications

This version suits single power units serving one consumer with changing demand, for example a hydraulic press or a clamping fixture. Because the pilot oil comes from its own delivery, the system can also be retrofitted into a plant where no pilot circuit was prepared. Operation assumes an HLP hydraulic fluid.
