Pumpenregelsystem SYDFE1-2X/028R-PRA12KC1-0479-B0X0XXX - Bosch Rexroth R901478717

Where the variable pump sits on a power unit with a shared pilot circuit, external supply is the simpler route. The PRA12KC1-0479-B0X0XXX version of the SYDFE1 takes pilot oil from outside and comes with a through-drive and a geared shaft (R).

Benefits

• Up to 84 l/min from 28 cm³ displacement, the swivel angle is commanded by an analog signal instead of being throttled down.
• Operating pressure up to 280 bar, pressure control and flow control run in the same unit.
• External pilot oil supply, KC1 controller version, matched to plants with a central pilot circuit.
• Through-drive fitted, a following pump can share the same motor.
• FKM seals with HLP fluid, the system stays tight at higher oil temperatures as well.

Technical data

Applications

Typical installations are presses and test rigs with several pumps running in parallel, where one unit leads on pressure and the others add flow. Setpoints arrive as analog signals from the machine controller, so no fieldbus is required. The ISO 2-hole flange allows direct mounting to a standard drive motor.
