Pumpenregelsystem SYDFE1-2X/045R-PRA12KD3-0000-A0X0XXX - Bosch Rexroth R900755618

A variable pump delivers only what the axis currently needs and saves the power a throttling circuit would waste. The SYDFE1-2X/045R-PRA12KD3-0000-A0X0XXX brings matched swivel angle and pressure control to a pump of size 45 cm3.

Advantages

• Swivel angle and pressure control at the pump, flow up to 117 l/min.
• Operating pressure up to 280 bar, displacement of 45 cm3 per revolution.
• Analogue control on 24 VDC, operation in master or slave mode is possible.
• Clockwise rotating version with geared shaft (R) and ISO 2-hole mounting flange.
• Through-drive included so a second pump can be added.
• Weight of 27.5 kg, FKM seals, HLP fluid, the control loop has its own supply.

Applications

The control system is used on power units that have to deliver changing flow rates at high pressure. Compared with a fixed pump and a throttle, oil heating stays lower because the pump only delivers the flow required. The through-drive allows a second pump to be mounted on the same shaft.
