Pumpenregelsystem SYDFEE-2X/045R-PPA12N00-0000-A2B0CXX - Bosch Rexroth R901470895

Cutting the energy bill of a hydraulic power unit starts at the pump rather than at a throttle. This SYDFEE-2X pump control system with 45 cm³ displacement runs swivel angle plus pressure control through on-board electronics, holds up to 280 bar operating pressure, and supplies up to 117 l/min without dumping oil across a relief valve.

Key benefits

• Swivel angle plus pressure control in one unit removes the constant bypass losses at 280 bar system pressure.
• Variable displacement of 45 cm³ per revolution yields up to 117 l/min at rated drive speed.
• On-board electronics with an analogue interface on 24 VDC, so no separate controller cabinet is required.
• Fitting key shaft plus ISO 2-hole flange allow a standard mount onto common electric motors.
• FKM seals together with HLP hydraulic fluid suit continuous duty on additive treated mineral oil.

Applications

The unit feeds injection moulding machines, presses plus test rigs whose long cycles call for full flow only part of the time. Master and slave operation links several units into one circuit. At 26 kg the assembly flanges straight onto the drive motor.

Manufacturer

Bosch Rexroth lists the unit as SYDFEE-2X/045R-PPA12N00-0000-A2B0CXX under material number R901470895. Characteristic curves, controller parameters plus terminal assignment appear in data sheet RD 30030 for the pressure and flow control system.
