Pumpenregelsystem SYDFEE-2X/018R-PPA12N00-0000-C2B0CX2 - Bosch Rexroth R901546045

Moving from a fixed displacement pump to a controlled variable pump depends less on the hydraulics than on the drive side. The SYDFEE-2X/018R-PPA12N00-0000-C2B0CX2 mounts on the existing bell housing with a fitting key shaft and an ISO 2-hole flange, providing up to 59 l/min at 280 bar from 18 cm³ displacement.

Key benefits

• Fitting key shaft for clockwise rotation - matches the common standard drive side, so a special adapter often becomes unnecessary.
• Preload valve rated 250 bar - one step above the 200 bar version, keeping the control circuit properly fed at high system pressure.
• Up to 59 l/min at 280 bar - the unit controls pressure and delivery itself, only the analog command value stays external.
• One connector for everything - 24 VDC supply and signal share the 12-pole connector (11 + PE) to EN 175201-804.
• FKM seals released for hydraulic fluid HLP - matched to mineral oil in continuous duty.
• 18.8 kg without through-drive - a compact single drive rather than a stacked pump tower.

Applications

In power units for presses, test rigs and machine tools this unit replaces the combination of fixed pump, proportional pressure valve and external amplifier. Master and slave operation is intended, so several units can share one pressure network. The drive has to turn clockwise, and displacement is varied through the swivel angle.
