Pumpenregelsystem SYDFE1-2X/071R-PRA12KC1-0479-A0X0XXX - Bosch Rexroth R901041859

To control pressure as well as flow on a single power unit, the SYDFE1-2X/071R-PRA12KC1-0479-A0X0XXX arrives as a matched package of variable pump in size 71 cm3, control valve and electronics, rated at 280 bar and up to 156 l/min.

Benefits

• Swivel angle control plus pressure control matched at the factory, master slave operation of several pumps supported.
• Variable displacement of 71 cm3, maximum flow 156 l/min at 280 bar operating pressure.
• Through-drive included, a second pump can be flanged on without an extra gearbox.
• External pilot oil supply, analogue communication, 24 VDC supply.
• Geared shaft (R), ISO 2-hole mounting flange, FKM seals for HLP fluid, 42.5 kg.

Applications

Control systems of this kind sit in injection moulding machines, presses and test rigs whose drive power is only needed during the working stroke. Because the pump swivels back at part load, heat losses as well as cooling demand drop noticeably. Rotation is clockwise, which matters when the motor is mounted.
