Pumpenregelsystem SYDFEE-2X/028R-PPA12N00-0000-A0A0CX3 - Bosch Rexroth R901110426
During the holding phase of an injection moulding machine, pressure must stand still for seconds while flow falls away. The SYDFEE-2X/028R-PPA12N00-0000-A0A0CX3 keeps the command value electronically to 280 bar, destroking its 28 cm³ pump accordingly. Preload valve 300 bar.

Description
Holding is the harder half of a cycle, because the pump swings back almost to zero while pressure has to stay put. The SYDFEE-2X/028R-PPA12N00-0000-A0A0CX3 governs exactly that transition electronically, working with a 300 bar preload valve.
Benefits
- 300 bar preload valve keeps control pressure above system pressure even when the pump is nearly destroked.
- Pressure plus swivel angle control inside the on-board electronics, analog command value, 24 VDC supply.
- 28 cm³ variable displacement, flow to 84 l/min, operating pressure to 280 bar.
- Fitting key shaft with ISO 2-hole flange, clockwise rotation, no through-drive.
- 23.8 kg weight, FKM seals, 12-pole connector (11 + PE) to EN 175201-804.
Application
The unit suits injection moulding machines, presses as well as clamping systems with long holding phases at high pressure. While holding, flow drops to leakage demand, so drive power follows down with it. The analog interface allows the command value to be shifted within the cycle.
Manufacturer
Bosch Rexroth, material number R901110426, product family SYDFEE. Loop behaviour during the holding phase is documented in data sheet RD 30030.
