Pumpenregelsystem SYDFEE-2X/045R-PPA12N00-0000-A2A0VX2 - Bosch Rexroth R901037480

Running a fixed pump against a relief valve all day mainly heats the oil. The pump control system SYDFEE-2X/045R-PPA12N00-0000-A2A0VX2 uses a variable pump of 45 cm³ instead, adjusting swivel angle to demand while supplying up to 117 l/min at 280 bar. The controller sits on the unit itself as on-board electronics.

Benefits

• 117 l/min at 280 bar from a variable pump of size 45 cm³ with clockwise rotation.
• Swivel angle and pressure control inside the on-board electronics, analog command value, master and slave operation possible.
• Preload valve at 250 bar as part of component series 2X.
• No through-drive and a fitting key shaft, which keeps the coupling to the motor short at the ISO 2-hole flange.
• 24 VDC and a 12-pole connector (11 + PE) to EN 175201-804, carrying supply and command value in one plug.
• FKM seals for hydraulic fluid HLP at a weight of 29.3 kg.

Technical data

Applications

The unit suits machines with strongly varying demand, such as injection moulding machines, presses and test rigs. Master and slave operation lets several pumps share one pressure level without fighting each other. As the controller comes with the unit, no separate control card is needed in the cabinet.

Manufacturer

The manufacturer is Bosch Rexroth, material number R901037480. Sizing data is listed in the data sheet for the pressure and flow control system, RD 30030.
