Pumpenregelsystem SYDFE1-2X/045R-PRA12KC1-0000-A0X0XXX - Bosch Rexroth R901148801
Instead of throttling a fixed pump, this pump system controls swivel angle and pressure directly at the variable pump. Frame size 45 cm3, 117 l/min maximum flow, 280 bar operating pressure, analogue control, clockwise rotation, 27.5 kg.

Description
Throttling a fixed displacement pump across a relief valve turns the difference into heat. The SYDFE1-2X/045R-PRA12KC1-0000-A0X0XXX takes the other route and controls swivel angle and pressure at the variable pump itself, 45 cm3 displacement at up to 280 bar.
Key benefits
- Swivel angle and pressure are controlled at the pump, so no throttling losses arise.
- Frame size 45 cm3 with a maximum flow of 117 l/min at 280 bar operating pressure.
- Variable displacement, clockwise rotation, a through-drive for a second pump is provided.
- Analogue communication, 24 VDC supply, wired through the valve connector and the position transducer connector.
- Geared shaft (R) as the shaft end, ISO mounting flange with 2 holes.
- 27.5 kg weight, FKM seals, HLP hydraulic fluid.
Applications
The pump system feeds power units of machine tools, presses and test rigs whose demand varies strongly across the cycle. During holding phases the pump swivels back, which lowers drive power and oil heating. The through-drive allows a second pump for an auxiliary circuit to be flanged on.
