Pumpenregelsystem SYDFEE-2X/028R-PPA12N00-0000-A0A0VXX - Bosch Rexroth R900773470

A fixed displacement pump behind a throttle turns every unused litre into heat. The SYDFEE-2X/028R-PPA12N00-0000-A0A0VXX works with variable displacement instead, supplies up to 84 l/min from size 28 and controls both swivel angle and pressure up to 280 bar on its own.

Benefits

• Up to 84 l/min on demand - displacement follows the command value rather than being dumped across a relief valve.
• 280 bar operating pressure with swivel angle control and pressure control in one unit.
• On-board electronics on 24 VDC, analog interface through a 12-pole connector (11 + PE) to EN 175201-804.
• FKM seals for HLP fluid plus a clockwise fitting key shaft without through-drive.
• 20.5 kg on an ISO 2-hole flange, so the unit fits common bell housings.

Application

Usual homes are power units for presses, injection moulding machines and test benches where pressure and flow change across the cycle. Because control sits inside the unit, the machine controller only has to send an analog value. In master and slave operation several units feed the same circuit.
