Pumpenregelsystem SYDFEE-2X/045R-PRA12KD3-0000-A0A1CXX - Bosch Rexroth R901059065

Space and drive power inside a power unit are limited, yet two circuits are required. The pump control system SYDFEE-2X/045R-PRA12KD3-0000-A0A1CXX carries a through-drive for a second pump to be flanged on, while controlling swivel angle and pressure up to 280 bar at a maximum flow of 117 l/min.

Benefits

• The through-drive lets 1 motor carry two pumps, which removes the second drive unit.
• Variable displacement of size 45 cm³ delivers up to 117 l/min at 280 bar.
• On-board control electronics run swivel angle control as well as pressure control, powered by 24 VDC.
• Analogue interface on a 12-pole connector (11 + PE) to EN 175201-804 makes an extra controller card unnecessary.
• Geared shaft (R), ISO 2-hole mounting flange and 27.5 kg of weight suit existing power units of series 2X.

Applications

The control system belongs in power units of presses, plastics machinery and test rigs that need a second circuit for cooling, tool clamping or auxiliary functions. Because the pump delivers only the flow that is called for, waste heat and cooling demand drop compared with a throttled fixed pump. The fluid is mineral oil of class HLP, sealed with FKM.
