Pumpenregelsystem SYDFEE-2X/028R-PPA12N00-0000-A0A0CXX - Bosch Rexroth R901144528

Letting a fixed pump deliver against a pressure valve simply heats the oil. The SYDFEE-2X/028R pump control system adjusts swivel angle instead and controls pressure directly at the pump, with 28 cm³ displacement and up to 280 bar.

Benefits

• Swivel angle and pressure control with on-board electronics mounted on the pump.
• Displacement of 28 cm³, delivery up to 84 l/min, maximum operating pressure 280 bar.
• Analogue setpoint and supply through one 12-pole (11 + PE) connector to EN 175201-804.
• Master and slave operation for plants running several pumps.
• Clockwise fitting key shaft, ISO two-hole mounting flange, no through-drive.
• FKM seals for HLP hydraulic fluid, mass 20.5 kg.

Application

The system suits the modernisation of existing power units that used to run a fixed pump in circulation. Because only the flow actually needed is delivered, heat losses in the tank drop. Direction of rotation, shaft end and flange pattern have to be matched against the drive before ordering.
