Pumpenregelsystem SYDFEE-2X/045R-PPA12N00-0000-A0B0VXX - Bosch Rexroth R901109016

A test rig alternates long dwell phases with short load peaks, so an uncontrolled pump simply heats the oil. This SYDFEE-2X/045R-PPA12N00-0000-A0B0VXX unit regulates swivel angle plus pressure electronically, works to 280 bar, and supplies up to 117 l/min as soon as the axis calls for volume.

Key benefits

• Electronic pressure control up to 280 bar cuts wasted power during dwell phases.
• Variable pump of 45 cm³ displacement reaching up to 117 l/min of flow.
• Analogue command value on a 24 VDC supply through a 12-pole plug to EN 175201-804.
• Clockwise rotation without through-drive keeps the installed length short.
• FKM seals cope with the oil temperatures typical of continuous test bench duty.

Technical data

Applications
