Pumpenregelsystem SYDFEE-2X/028R-PRA12N00-0000-A0B0CXX - Bosch Rexroth R901485481

The cooling capacity a plant needs follows the oil it circulates uselessly. This control system adjusts its 28 cm³ displacement to demand, delivers up to 84 l/min and draws almost no drive power during the holding phase, which allows a smaller cooler.

Benefits

• Variable displacement of 28 cm³, flow up to 84 l/min.
• Pressure control up to 280 bar directly at the pump, with no permanent blow-off across a pressure valve.
• Less waste heat in the tank, so less cooling capacity is required.
• On-board electronics with an analogue interface, 24 VDC supply.
• Geared shaft (R), ISO 2-hole mounting flange, clockwise rotation, without through-drive.
• FKM seals for HLP hydraulic fluid, weight 20.5 kg.

Technical data

Applications

The system is used on plastics machines, machine tools and test benches with strongly varying oil demand. Without a through-drive the unit is shorter and fits into narrow power unit housings. The geared shaft (R) requires a matching coupling hub on the motor.
