Pumpenregelsystem SYDFE1-2X/071L-PRA12KD3-0000-A0X0XXX - Bosch Rexroth R901472075

Throttling flow at a valve turns the surplus power into heat in the oil. The SYDFE1-2X/071L-PRA12KD3-0000-A0X0XXX pump control system instead adjusts the swivel angle of the variable pump and delivers up to 156 l/min at 280 bar from a displacement of 71 cm³.

Benefits

• Variable pump with 71 cm³ displacement, flow up to 156 l/min at 280 bar operating pressure
• Swivel angle and pressure control in one system, so flow is generated rather than throttled away
• Master and slave operation is possible, letting several pumps feed one consumer
• Through-drive fitted, so a second pump can be added without an extra gearbox
• Geared shaft (R) and ISO 2-hole mounting flange, matching common drive motors
• FKM seals and HLP hydraulic fluid, analog control on a 24 V DC supply

Applications

The system sits in power units of presses, injection moulding machines and test rigs where demand and pressure change widely. Since the pump only delivers what is needed, heat input and cooling load fall in part load operation. Direction of rotation is counterclockwise, which has to be considered when choosing the drive motor.
