Pumpenregelsystem SYDFE1-3X/071R-VRB22U00-0000-A0X0XXX - Bosch Rexroth R901135311

Setting pressure plus flow at the pump instead of at a valve saves waste heat across the whole circuit. This control system combines a variable pump of 71 cm³ size with its matching control, delivers up to 128 l/min and works to 280 bar operating pressure.

Benefits

• Swivel angle control plus pressure control at the pump avoid a permanent bleed loss over a pressure valve.
• 71 cm³ displacement at up to 128 l/min maximum flow against 280 bar.
• Analog control on 24 VDC, master as well as slave operation across several pumps.
• A through-drive is fitted, so a second pump can be flanged on directly.
• Geared shaft (R), clockwise rotation on an ISO 4-hole mounting flange, mass 49 kg, FKM seals for hydraulic fluid class HLP.

Applications

Systems of this kind run in presses, injection moulding machines and test rigs with strongly changing demand. Because the pump delivers only what the axis draws, oil stays cooler while the tank can stay smaller. Master-slave operation allows several units to feed one shared circuit.
