Pumpenregelsystem SYDFE1-2X/071R-PRA12KD3-0479-A0X0XXX - Bosch Rexroth R901429293

Two pumps on one motor save a drive, space along with a coupling. This version of the SYDFE1 range therefore carries a through-drive while taking its pilot oil from an external circuit, at 71 cm³ of displacement, flow to 156 l/min plus a maximum operating pressure of 280 bar.

Benefits

• Through-drive fitted, so a second pump runs from the same drive motor
• External pilot oil makes the control loop independent of the current delivery pressure
• Displacement of 71 cm³ with flow to 156 l/min at a maximum operating pressure of 280 bar
• Geared shaft (R) plus ISO 2-hole mounting flange form a standardised mechanical interface
• FKM seals for HLP hydraulic fluid, clockwise rotation, mass 42.5 kg

Application

Meant for power units where a second pump handles cooling, filtration or an auxiliary circuit. External pilot supply keeps the control loop alive even when the pump sits near zero swivel angle. Typical installations are large presses plus test fields.
