Pumpenregelsystem SYDFEE-2X/028R-PPA12N00-0000-A0A0EX2 - Bosch Rexroth R901235284

Compact hydraulic power units have to run as efficiently as large ones. This SYDFEE-2X pump control system with 28 cm³ displacement supplies up to 84 l/min, holds 280 bar operating pressure, and manages swivel angle plus pressure from its own electronics, backed by a preload valve set at 250 bar.

Key benefits

• Displacement of 28 cm³ giving up to 84 l/min suits compact power units.
• A preload valve at 250 bar steadies the circuit below the 280 bar rated pressure.
• Electronic pressure plus swivel angle control taking an analogue command value on 24 VDC.
• Mass of 23.8 kg against 26 kg for size 45 lowers the load on bell housing plus coupling.
• Fitting key shaft in an ISO 2-hole flange mounts without a special adapter.

Applications

The unit feeds compact presses, clamping systems plus test assemblies whose flow demand swings widely. Master and slave operation leaves room to add a second pump later. HLP hydraulic fluid is intended, the seals are FKM.

Manufacturer

Bosch Rexroth lists the unit as SYDFEE-2X/028R-PPA12N00-0000-A0A0EX2 under material number R901235284. Sizing data, curves plus notes on the preload valve appear in data sheet RD 30030 for the pressure and flow control system.
