Pumpenregelsystem SYDFEE-2X/028R-PRA12KC1-0000-A0A0VX2 - Bosch Rexroth R901430494

With pressure control across a relief valve, a system pays for every holding phase in waste heat. The SYDFEE-2X/028R-PRA12KC1 pump control system moves control to the pump itself and holds 280 bar operating pressure at a displacement of 28 cm3 and up to 84 l/min flow.

Key benefits

• Pressure control at the pump instead of throttling, which cuts power loss during holding phases.
• Variable displacement up to 28 cm3 with swivel angle control as the base function.
• On-board electronics with analog command, so no external controller is required.
• Preload valve at 250 bar and 280 bar nominal pressure, matched to HLP fluid.
• Through-drive and ISO 2-hole flange accept add-on pumps and standard motors.
• FKM seals for higher temperature resistance than NBR in continuous duty.

Applications

Typical applications are power units with long holding phases, for instance clamping and testing equipment, and systems running several pumps in a master and slave group. Its own supply makes the unit independent of a separate control circuit feed. Shaft end and flange follow the series, so the unit fits existing size 28 drives.
