Pumpenregelsystem SYDFEE-2X/045R-PRA12N00-0000-A2A0VXX - Bosch Rexroth R901212791

Every throttling point in the circuit turns into heat that has to be cooled away again. The SYDFEE-2X/045R-PRA12N00-0000-A2A0VXX pump control system adjusts the variable pump itself through swivel angle and pressure, up to 280 bar and 117 l/min at a size of 45 cm³.

Benefits

• 280 bar operating pressure and up to 117 l/min from a variable pump of size 45 cm³.
• On-board electronics on 24 V DC with an analog interface through a 12-pole connector (11 + PE) to EN 175201-804.
• Swivel angle control, pressure control and master or slave operation, so several pumps can run as a group.
• Geared shaft (R) with clockwise rotation on the ISO 2-hole flange, no through-drive, weight 26 kg.
• FKM seals for HLP hydraulic fluid.

Applications

The system feeds presses, injection moulding machines and test rigs where pressure and flow change within the cycle. Because the pump delivers only what is called for, power loss and cooling demand drop. In master and slave operation several units follow one common command value.
