Pumpenregelsystem SYDFE1-2X/045R-PRA12N00-0000-A0X0XX3 - Bosch Rexroth R901554852

Where a fixed displacement pump turns its surplus power into heat across the relief valve, this system adjusts the swivel angle and therefore the delivered flow to actual demand. The SYDFE1 with 45 cm³ and up to 117 l/min works to 280 bar and combines pressure control and swivel angle control in one unit.

Benefits

• Swivel angle control and pressure control in one unit, rated to 280 bar operating pressure.
• 45 cm³ displacement and up to 117 l/min cover medium sized power units.
• Variable displacement reduces power loss compared with a fixed pump.
• Master and slave operation allow several pumps to work together.
• A 300 bar preload valve and an own supply belong to the system scope.
• FKM seals and release for HLP hydraulic fluid, ISO 2-hole mounting flange.

Applications

The control system is used in power units for presses, test benches and plastics machinery whose demand for pressure and flow varies strongly within a cycle. The geared shaft with clockwise rotation matches the usual drive motors in this size. At 29.3 kg the unit needs a lifting aid during assembly.
