Pumpenregelsystem SYDFEE-2X/045R-PRA12KD3-0000-A0A1EXX-006 - Bosch Rexroth R901029160

Sizing a power unit for peak demand wastes energy through the rest of the cycle. The SYDFEE pump control system of 45 cm³ displacement solves that on the pump itself, working up to 280 bar and 117 l/min with the closed loop running in on-board electronics. Swivel angle and pressure setpoints arrive as analog signals on the 12-pole connector.

Key benefits

• 280 bar maximum operating pressure at 45 cm³ displacement and up to 117 l/min
• On-board electronics mounted on the pump handle swivel angle and pressure control without an external controller
• Analog setpoint input on a 12-pole connector (11 + PE) to EN 175201-804, supply 24 VDC
• Variable pump, clockwise rotation, with through-drive for a second pump on the same shaft
• ISO 2-hole mounting flange and geared shaft (R) shaft end
• FKM seals for HLP hydraulic fluid, weight 27.5 kg

Applications

The system suits power units for presses, injection moulding machines and test benches with strongly varying demand across the cycle. Because the pump only swivels as far as the setpoint requires, the throttling losses of a fixed pump with relief control disappear. The through-drive frees a second circuit from the same drive motor, and coupled drives run in master/slave mode.
