Pumpenregelsystem SYDFEE-2X/045R-PRA12N00-0479-A0A0CXX - Bosch Rexroth R901376834

Throttling losses appear wherever a fixed displacement pump works against a pressure valve. The SYDFEE-2X/045R-PRA12N00-0479-A0A0CXX pump control system instead regulates swivel angle and pressure directly at the variable pump, delivering up to 117 l/min at a maximum operating pressure of 280 bar.

Benefits

• 117 l/min maximum flow from a variable pump of size 45 cm³.
• 280 bar operating pressure under closed-loop control.
• Swivel angle and pressure control with master and slave operation through the on-board electronics.
• Analog command value input at 24 VDC, 12-pole connector (11 + PE) to EN 175201-804.
• FKM seals for hydraulic fluid HLP, geared shaft (R) and an ISO 2-hole mounting flange.

Application

The system is used in power units for plastics and forming machinery where flow and pressure follow actual demand. Master and slave operation allows several pumps to feed one common circuit. The pump turns clockwise and has no through-drive, and the unit weighs 28 kg.

Manufacturer

Bosch Rexroth material number R901376834. Characteristic curves and commissioning notes are covered by datasheet RD 30030 for the pressure and flow control system.
