Pumpenregelsystem SYDFE1-2X/071R-PRA12N00-0479-B0X0XXX - Bosch Rexroth R901271238

The SYDFE1-2X/071R exists to match oil supply to demand. Its controller adjusts the swivel angle so that pressure and flow follow the analog command value, up to 280 bar operating pressure at 156 l/min. No surplus oil is relieved, so waste heat in the tank stays low.

Benefits

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

Applications

Injection moulding machines, presses and power units with strongly varying demand between rapid traverse and holding are the classic case. At 280 bar rated pressure one unit covers pressure build-up as well as follow-up motion. The two-hole ISO flange allows a swap against an existing pump of the same size.

Manufacturer

Bosch Rexroth assigns material number R901271238 to this version. Data sheet RE 30011-B on pressure and flow control carries the control curves as well as installation notes.
