Pumpenregelsystem SYDFEE-2X/028R-PRA12N00-0000-A0A0CX2 - Bosch Rexroth R901308154

A test power unit spends much of its life at part load, which is exactly where a throttled fixed pump wastes the most energy. The SYDFEE-2X/028R-PRA12N00-0000-A0A0CX2 trims swivel angle plus pressure of its 28 cm³ pump electronically, handling load changes without rebuilding anything.

Benefits

• Electronic command tracking for pressure as well as swivel angle, analog input, 24 VDC supply.
• Up to 84 l/min at 280 bar from a variable pump of 28 cm³ displacement.
• Geared shaft (R) for positive torque transfer on drives that start often.
• 250 bar preload valve secures pilot oil supply across the whole pressure range.
• FKM seals for longer life in warm oil, 23.8 kg, HLP hydraulic fluid.

Application

The unit is intended for test rigs, simulators plus production cells with strongly varying oil demand. As the pump supplies only what is drawn, the tank stays cooler, which allows a smaller cooler. Master and slave operation is available when several units share a line.
