Pumpenregelsystem SYDFE1-2X/071R-PPA12N00-0479-A0X0XXX - Bosch Rexroth R900757655

The system holds pressure and flow of a variable 71 cm3 pump on the analog command value, up to 280 bar at 156 l/min. Drive is through a fitting key shaft turning clockwise, which lets an installed unit be replaced without reworking the coupling.

Benefits

• Fitting key shaft end, clockwise rotation, ISO 2-hole mounting flange
• Variable displacement of 71 cm3 with flow up to 156 l/min
• Swivel angle plus pressure control to 280 bar operating pressure, master and slave operation supported
• Analog control at 24 VDC, wired through valve connector plus position transducer connector
• FKM seals for HLP fluid, no through-drive, mass of 42.5 kg

Applications

The unit feeds presses, test benches and machine tools whose demand alternates between rapid traverse and pressure holding. Because only the flow actually drawn is delivered, oil heating stays moderate. For a swap against an older pump, flange, direction of rotation and shaft profile are what count.

Manufacturer

Bosch Rexroth uses material number R900757655 for this build. Control curves as well as mounting positions appear in data sheet RE 30011-B on pressure and flow control.
