Pumpenregelsystem SYDFEE-2X/045R-PRA12KD3-0000-A2A0FXX - Bosch Rexroth R900730666

For power units whose rapid stroke needs more flow than a size 28 can give, this pump control system is the next step: 45 cm³ displacement provides up to 117 l/min and the operating pressure reaches 280 bar. Swivel angle and pressure control sit on the unit as on-board electronics.

Benefits

• Up to 117 l/min from 45 cm³ displacement, roughly a third more flow than size 28 at the same nominal pressure.
• Operating pressure up to 280 bar with variable displacement, so the motor draws only the power actually needed.
• On-board electronics provide swivel angle control, pressure control and master/slave function without an external amplifier.
• Through-drive fitted, a second pump can be mounted directly.
• FKM seals and HLP fluid for warm continuous duty.
• 24 VDC supply and analog command value through a 12-pole connector (11 + PE) according to EN 175201-804.

Applications

The unit feeds presses, test rigs and larger clamping or feed axes that combine a rapid stroke with pressure holding in one cycle. Because the swivel angle follows demand, losses during the rapid stroke stay low and the oil runs cooler. The ISO 2-hole flange suits common bell housings.
