Pumpenregelsystem SYDFEE-2X/028R-PPA12N00-0000-A2A0VX3 - Bosch Rexroth R901276586

A forming tool needs force across the whole drawing time rather than flow. The SYDFEE-2X/028R-PPA12N00-0000-A2A0VX3 regulates the pressure of its 28 cm³ pump electronically, destroking far enough that only leakage is replaced.

Benefits

• Pressure control to 280 bar with the pump almost destroked, made for long holding phases.
• 300 bar preload valve secures control pressure at the top of the pressure range.
• Flow to 84 l/min for rapid travel, followed by demand based reduction of the swivel angle.
• Fitting key shaft with ISO 2-hole flange, clockwise rotation, no through-drive, 23.8 kg.
• Analog command value on a 12-pole connector (11 + PE) to EN 175201-804, 24 VDC supply.

Application

The unit fits drawing presses, riveting stations plus clamping fixtures where force is held long as well as travel is rare. Since the pump barely delivers while holding, heating plus energy demand drop clearly against a throttled solution. The pressure setpoint can be shifted within the cycle through the analog input.
