Pumpenregelsystem SYDFE1-2X/045R-PRA12KD3-0479-A0X0XXX - Bosch Rexroth R901338413

A fixed pump always delivers full flow and heats the oil as soon as the machine asks for little. The SYDFE1-2X/045R-PRA12KD3-0479-A0X0XXX pump control system works with a variable 45 cm³ displacement instead, providing up to 117 l/min at a maximum of 280 bar under an analogue command value.

Benefits

• Variable 45 cm³ displacement delivers only the flow actually requested, up to 117 l/min.
• Operating pressure up to 280 bar, HLP hydraulic fluid, FKM seals.
• Analogue control at 24 VDC, wired through a valve connector and a valve position transducer connector.
• Clockwise geared shaft drive on an ISO 2-hole mounting flange, system mass 29.5 kg.
• A through-drive is fitted, so a second pump can share the same drive shaft.

Application

Used in hydraulic power units for machine tools, presses and test rigs with strongly varying demand. Because the pump swivels back, drive power and oil temperature drop in part load. The through-drive allows a second circuit without a second motor.
