Pumpenregelsystem SYDFEE-2X/028R-PRA12KD3-0000-A0A0CX2-002 - Bosch Rexroth R901285829

When circuit pressure drops abruptly, the variable pump loses its restoring force. This version of the SYDFEE-2X/028R therefore includes a preload valve rated 250 bar and controls swivel angle and pressure of 28 cm³ displacement at up to 84 l/min.

Benefits

• Integrated preload valve 250 bar, the circuit stays above minimum pressure while unloading.
• 28 cm³ variable displacement, up to 84 l/min at 280 bar operating pressure.
• Swivel angle and pressure control through on-board electronics with an analogue command value.
• Through-drive fitted, geared shaft (R), clockwise rotation, ISO 2-hole mounting flange.
• FKM seals and hydraulic fluid HLP, 24 V DC supply through a 12-pole connector.
• 25.3 kg weight, roughly three kilograms more than the version without a preload valve.

Applications

The variant suits presses and injection moulding machines with fast unloading cycles as well as systems with long suction lines. The minimum pressure keeps the pump lubricated during idling. Master and slave operation stays available as on the other versions of the series.
