Pumpenregelsystem SYDFE1-2X/071R-PRA12KC1-0000-C0X0XXX - Bosch Rexroth R901090369

Matching the flow of a power unit to real demand means replacing throttling with displacement control. The SYDFE1-2X/071R-PRA12KC1 combines a variable axial piston pump of 71 cm3 frame size with swivel angle and pressure control, providing up to 156 l/min at 280 bar operating pressure.

Benefits

• Variable displacement of 71 cm3 supplies only the flow the machine actually calls for.
• Swivel angle control and pressure control in one system, master and slave operation are provided for.
• 280 bar rated pressure and 156 l/min maximum flow cover medium power unit ratings.
• Analogue communication at 24 VDC, the control card runs on its own supply.
• A through drive is fitted, so a second pump can be added without a separate motor.
• Geared shaft (R) and an ISO 2-hole flange match the usual mounting situation, total mass 40.5 kg.

Application

The system sits in power units of machine tools, presses and test rigs with strongly varying oil demand. Because the pump swivels back instead of throttling, waste heat drops and the cooler can be smaller. Clockwise rotation is fixed and must be observed when mounting the motor.
