Pumpenregelsystem SYDFEE-2X/045R-PRA12KD3-0000-A0A0EXX - Bosch Rexroth R901113726

A drive that sets flow through the variable pump instead of an orifice does not turn the surplus power into heat. The SYDFEE-2X/045R controls swivel angle and pressure electrically, delivers up to 117 l/min and works up to 280 bar operating pressure.

Key benefits

• Swivel angle and pressure control set electrically, no throttling losses in a bypass.
• Flow up to 117 l/min from 45 cm3 displacement, nominal pressure 280 bar.
• On-board electronics with an analog command interface, 24 VDC supply.
• Master and slave operation possible, several units feed one circuit in coordination.
• Through-drive fitted, a second pump can be flanged on.
• Geared shaft (R), clockwise rotation, ISO 2-hole mounting flange, FKM seals for HLP fluid.

Applications

The system supplies pressure and flow to presses, injection moulding machines and test rigs whose demand varies strongly across the cycle. Because only the requested flow is delivered, cooling demand and connected load both drop. The through-drive allows a second pump on the same motor. At 27.5 kg the unit still mounts on an ISO 2-hole flange.
