Pumpenregelsystem SYDFEE-2X/028R-PRA12KC1-0000-A0B0VX3 - Bosch Rexroth R901058260

Where a power unit has to supply flow on demand and still hold a high preload in the circuit, this version fits: the preload valve works at 300 bar while the variable size 28 cm³ unit supplies up to 84 l/min at 280 bar operating pressure.

Benefits

• Preload valve rated 300 bar for circuits running high back pressure.
• Up to 84 l/min from 28 cm³ displacement at 280 bar nominal pressure.
• On-board electronics handle swivel angle control, pressure control and master/slave operation, so no external amplifier is required.
• Through-drive as standard, allowing a second pump on the same drive.
• FKM seals with HLP fluid, suitable for high sustained tank temperatures.
• Analog command interface and 24 VDC through a 12-pole connector (11 + PE) according to EN 175201-804.

Applications

The system is used in power units for forming machines, clamping equipment and test installations that alternate between holding pressure and moving. The 300 bar preload keeps the circuit stable when downstream consumers feed back. Master/slave operation lets several units share one pressure line.
