Pumpenregelsystem SYDFEE-2X/045R-PRA12N00-0000-A0A0CXX - Bosch Rexroth R901273641

A power unit that runs permanently against its pressure relief valve gets hot and loud. The SYDFEE-2X/045R-PRA12N00-0000-A0A0CXX replaces that operating case with electronic control of swivel angle and pressure, at a maximum flow of 117 l/min and 280 bar operating pressure.

Benefits

• Swivel angle control together with pressure control inside the unit keeps the pump nearly flow-free while holding 280 bar.
• Size 45 cm³ with variable displacement, flow up to 117 l/min.
• Analogue command value into the on-board electronics, supply 24 VDC through a 12-pole connector (11 + PE) to EN 175201-804.
• Clockwise geared shaft (R) with ISO 2-hole flange, installation dimensions of series 2X.
• 26 kg without through-drive, FKM seals for mineral oil of class HLP.

Technical data

Applications

This unit is needed in machine tools, test rigs and presses whose power unit stands in the shop and whose heat input must stay limited. Even during long holding phases at high pressure, power draw stays low because the pump swivels back. Cooling and filtration follow the requirements of HLP fluid.
