Pumpenregelsystem SYDFEE-2X/028R-PPA12N00-0000-A0B0VX3 - Bosch Rexroth R900759279

In a fixed displacement power unit the difference between demand and delivery turns into heat at the relief valve. The SYDFEE-2X/028R-PPA12N00-0000-A0B0VX3 pump control system instead regulates swivel angle and pressure of the variable pump directly and provides up to 84 l/min at an operating pressure of 280 bar.

Benefits

• 28 cm³ variable displacement, so delivery follows the actual demand of the machine.
• Swivel angle and pressure control through on-board electronics with their own supply.
• Flow up to 84 l/min at a maximum operating pressure of 280 bar.
• Analog interface and master/slave operation for combining several pumps.
• Fitting key shaft, clockwise rotation, ISO 2-hole mounting flange, no through-drive.
• 23.8 kg, FKM seals, HLP hydraulic fluid, 12-pole connector (11 + PE).

Application

The control system is used in machine tools, presses and test rigs with strongly varying oil demand. Master/slave operation allows several pumps on one tank. A 300 bar preload valve belongs to this build.
