Pumpenregelsystem SYDFEE-2X/028R-PRA12KC1-0000-A0B0VX2 - Bosch Rexroth R901506419

Presses and test rigs that need pressure and flow set independently get the complete control loop at the drive with this pump control system. The variable unit of size 28 cm³ delivers up to 84 l/min and works up to 280 bar operating pressure, with swivel angle and pressure handled by on-board electronics instead of an external amplifier card.

Benefits

• Up to 84 l/min from 28 cm³ displacement, which keeps the drive package small.
• Operating pressure up to 280 bar, the preload valve of this version opens at 250 bar.
• Swivel angle control, pressure control and master/slave operation come from the on-board electronics, so no separate controller board is needed in the cabinet.
• Through-drive included, a second pump can be flanged on without its own motor.
• FKM seals and HLP hydraulic fluid suit continuous duty at high oil temperature.
• 24 VDC supply through a 12-pole connector (11 + PE) according to EN 175201-804, analog command value.

Applications

Typical uses are power units on presses, injection moulding machines and test benches where flow should follow actual demand instead of being throttled into heat. In master/slave operation two control systems feed one common pressure line. The ISO 2-hole flange and geared shaft fit standard motors.
