Pumpenregelsystem SYDFE1-2X/071R-PRA12KD3-0000-C0X0XXX - Bosch Rexroth R901090201

On power units with alternating load phases, the control card decides how quickly pressure follows the command value. The SYDFE1-2X/071R-PRA12KD3 uses a variable pump of 71 cm3 frame size for this, holds 280 bar rated pressure and delivers up to 156 l/min.

Benefits

• Card version PRA12KD3 inside an otherwise identical system, so mounting dimensions and spare parts stay the same across the series.
• 280 bar operating pressure with pressure control and swivel angle control from one source.
• Up to 156 l/min at 71 cm3 displacement, flow follows demand.
• Analogue control at 24 VDC, master and slave operation are possible.
• The through drive allows a second pump on the same drive.
• FKM seals and HLP hydraulic fluid suit higher oil temperatures in continuous duty.

Application

The control system belongs on power units whose consumers switch in short cycles between rapid traverse and pressure holding, for example in presses and clamping devices. Swivelling the pump back cuts power loss noticeably during holding phases. Geared shaft (R), ISO 2-hole flange and 40.5 kg mass govern the installation plan.
