Pumpenregelsystem SYDFEE-2X/028R-PPA12N00-0000-A0A1VX2 - Bosch Rexroth R901390132

Two variable pumps on one network fight each other as soon as each follows its own pressure controller. The SYDFEE-2X/028R-PPA12N00-0000-A0A1VX2 is prepared for master and slave operation, splitting demand of up to 84 l/min cleanly.

Benefits

• Master and slave capable control over the analog interface, command value plus enable on the 12-pole connector (11 + PE).
• Swivel angle plus pressure control in one unit, operating pressure to 280 bar.
• 250 bar preload valve as the middle setting, balanced between control pressure reserve as well as power loss.
• 28 cm³ variable pump rated to 84 l/min, clockwise rotation, no through-drive.
• Fitting key shaft, ISO 2-hole flange, 23.8 kg, FKM seals.

Application

The build suits power units with two or more pumps feeding a shared pressure line, such as large presses plus test fields. Within the group the master leads on pressure while the slaves add flow. Control stays stable because the units no longer drive each other upward.
