Pumpenregelsystem SYDFE1-2X/045L-PPA12N00-0000-A0X0XX2 - Bosch Rexroth R901022807

Controlling the pressure and flow of a variable pump electrically only works when pump, control valves and position transducer match each other. The SYDFE1-2X/045L-PPA12N00-0000-A0X0XX2 supplies that unit ready to fit, with 45 cm³ displacement per revolution, up to 117 l/min and 280 bar nominal pressure.

Benefits

• Swivel angle control and pressure control in one system remove the need to build it up from separate parts.
• 45 cm³ displacement and up to 117 l/min at a maximum operating pressure of 280 bar.
• Master and slave operation allow several pumps to follow one shared command value.
• A 250 bar preload valve plus its own supply let the system run without an external pilot circuit.
• Fitting key shaft, ISO 2-hole mounting flange, counterclockwise rotation, FKM seals, weight 29.3 kg.

Technical data

Applications

The control system feeds presses, injection moulding machines and test rigs whose demand changes strongly over a cycle. Since the pump delivers only what the control asks for, spill over a relief valve disappears together with the heat it produced. Hydraulic fluid is mineral oil of class HLP.
