Pumpenregelsystem SYDFE1-2X/071R-PRA12KD5-0000-C0X0XXX - Bosch Rexroth R901052645

A power unit that works permanently against a relief valve simply burns oil. The SYDFE1-2X/071R-PRA12KD5 pump control system avoids that by swivelling back the 71 cm3 frame size pump and setting operating pressure up to 280 bar through its control card.

Benefits

• Swivelling back instead of throttling reduces waste heat, so the cooling circuit can be smaller.
• Card version PRA12KD5 within series 2X, at 71 cm3 displacement and 280 bar rated pressure.
• Maximum flow of 156 l/min, enough for medium sized groups of consumers.
• Analogue interface at 24 VDC, swivel angle control and pressure control in one system.
• Through drive as standard, an auxiliary pump can run without a second motor.
• FKM seals, ISO 2-hole flange and geared shaft (R) at 40.5 kg total mass.

Application

Intended duties are machine tools and test units with long holding phases and short rapid strokes. Because rotation is clockwise, the drive motor has to be chosen accordingly. Characteristic curves for sizing are given in the series data sheets.
