Pumpenregelsystem SYDFE1-2X/028R-PRA12KC3-0567-C0X0XXX - Bosch Rexroth R900746871

Where a second pump has to run off the same motor but the power unit has no pilot circuit of its own, the combination of through-drive and self supply fits. That is exactly what the PRA12KC3-0567-C0X0XXX version of the SYDFE1 delivers at 280 bar operating pressure.

Benefits

• Own pilot oil supply, the power unit needs no separate control circuit for the adjustment.
• Through-drive at 28 cm³ displacement, a following pump is flanged on without extending the drive train.
• Flow up to 84 l/min at a maximum of 280 bar, rapid traverse and holding phase run without switching valves.
• Geared shaft (R), clockwise rotation, ISO 2-hole flange, the motor interface is unambiguously defined.
• 24 kg weight with FKM seals, laid out for HLP fluid in continuous duty.

Applications

The control system is used in power units for forming technology and in test rigs where flow demand jumps sharply between rapid traverse and holding phase. The through-drive lets a second pump supply an auxiliary circuit, for cooling or clamping. Setpoints for pressure and swivel angle arrive as analog signals from the machine controller.
