Pumpenregelsystem SYDFEE-2X/028R-PPA12N00-0000-A0B1VX3 - Bosch Rexroth R901073031

If pressure in the circuit drops too far, the variable pump draws air or loses control quality. This version sets the preload valve to 300 bar, holding enough inlet pressure through fast unloading, with the pump rated at 280 bar nominal pressure.

Benefits

• 300 bar preload valve, laid out for circuits with fast pressure changes
• 28 cm³ variable displacement, 84 l/min maximum flow
• Swivel angle control, pressure control by the on-board electronics, master and slave operation possible
• Fitting key shaft, ISO 2-hole mounting flange, clockwise rotation, no through drive
• Analog command on 24 VDC, 12-pole connector (11 + PE), FKM seals, 23.8 kg

Application

A match for presses, injection moulding machines with frequent steps of pressure, of flow within the cycle. The higher preload protects the pump during a fast change from holding pressure to rapid traverse. HLP is the intended hydraulic fluid.
