Pumpenregelsystem SYDFEE-2X/028R-PRA12N00-0479-A2A0CXX - Bosch Rexroth R901291014

A power unit that works permanently against a relief valve heats the oil and burns electricity. The SYDFEE-2X/028R-PRA12N00-0479-A2A0CXX controls swivel angle and pressure of the variable pump electronically and delivers up to 84 l/min at 280 bar.

Benefits

• Variable displacement of 28 cm³ per revolution, flow up to 84 l/min.
• Pressure and swivel angle control by on-board electronics, commanded through analogue signals.
• 280 bar operating pressure with clockwise rotation and a geared shaft (R).
• ISO 2-hole mounting flange, version without through-drive.
• 12-pole connector (11 + PE) to EN 175201-804, 24 V DC supply.
• 22.5 kg weight, FKM seals, HLP hydraulic fluid.

Application

Systems like this sit in power units for presses, injection moulding machines and test rigs whose demand swings widely across the cycle. Because the pump only delivers the flow requested, power loss and oil heating drop. Master and slave operation allows several pumps to feed one common circuit.
