Pumpenregelsystem SYDFEE-2X/028R-PRA12KC3-0000-A0A0VX2 - Bosch Rexroth R901551180

A fixed pump with a relief valve turns surplus power into heat. The pump control system SYDFEE-2X/028R-PRA12KC3-0000-A0A0VX2 controls swivel angle plus pressure instead, so with 28 cm³ displacement at 280 bar nominal pressure only the flow actually needed, up to 84 l/min, is delivered.

Benefits

• Controlled swivel angle with controlled pressure, plus master/slave operation of several units.
• Variable displacement of 28 cm³, flow up to 84 l/min, operating pressure up to 280 bar.
• On-board control electronics with its own 24 VDC supply, analogue communication.
• Preload valve 250 bar, component series 2X as stated by the manufacturer.
• Clockwise rotation, geared shaft (R), through-drive available, ISO 2-hole mounting flange.
• FKM seals for hydraulic fluid HLP, 12-pole connector (11 + PE) to EN 175201-804, mass 26 kg.

Technical data

Applications

The system is built for power units whose demand swings widely across the cycle, such as presses, plastics machinery plus test rigs. The through-drive allows a second pump on the same drive. In master/slave operation several units can follow one common demand.
