Pumpenregelsystem SYDFE1-2X/071R-PRA12N00-0000-B0X0XXX - Bosch Rexroth R901292721

Rather than burning surplus oil across a relief valve, this pump control system sets the swivel angle of a variable pump to match demand: 71 cm³ displacement, up to 156 l/min, 280 bar operating pressure, analog control.

Advantages

• Swivel angle control together with pressure control in one package, no detour through a bypass valve.
• 71 cm³ displacement yields up to 156 l/min at 280 bar maximum operating pressure.
• Own pilot oil supply, so no additional pilot circuit has to come from the plant.
• Master operation as well as slave operation lets several pumps follow one setpoint.
• Clockwise geared shaft (R) on an ISO 2-hole flange, FKM seals for HLP hydraulic fluid.

Applications

Used on injection moulding machines, presses, test rigs with strongly varying demand. The 37.5 kg unit replaces a fixed pump along with its throttling losses, which lowers oil temperature in continuous duty.
