Pumpenregelsystem SYDFEF-2X/028R-PRA12N00-0000-A0ANVXX - Bosch Rexroth R901553505

A controller that sets pressure and flow digitally over a fieldbus needs pump electronics with a bus connection rather than an analog command card. The SYDFEF-2X/028R-PRA12N00-0000-A0ANVXX regulates a variable pump of 28 cm³ size up to 280 bar operating pressure and delivers up to 84 l/min.

Benefits

• Digital bus connection for command values from the machine controller, 24 VDC supply.
• 84 l/min maximum flow from a variable pump with 28 cm³ displacement.
• Maximum operating pressure 280 bar with swivel angle control, pressure control and torque limitation.
• On-board control electronics, 7-pole connector (6 + PE) according to EN 175201-804, 20.5 kg weight.
• FKM seals for HLP hydraulic fluid, geared shaft (R), ISO 2-hole mounting flange, clockwise rotation without through-drive.

Technical data

Applications

The control system sits in power units for plastics machinery, test rigs and special purpose machines whose controller already communicates over a fieldbus. Torque limitation protects the drive motor when high pressure and high flow are demanded at the same time. Master and slave operation allows several pumps to work on one circuit. The pump turns clockwise and has no through-drive.
