Pumpenregelsystem SYDFEE-2X/045R-PRA12KC1-0000-A2A0VXX - Bosch Rexroth R901038403

When one power pack has to feed two circuits, a second motor and pump assembly costs space, money and another coupling. The SYDFEE-2X/045R-PRA12KC1-0000-A2A0VXX is built with a through-drive, so a follow-on pump runs on the same drive shaft, while the unit itself provides up to 117 l/min at 280 bar from 45 cm³ displacement.

Key benefits

• Through-drive fitted - a second pump runs on the same shaft, leaving the motor position in the power pack free.
• 117 l/min at 280 bar - enough delivery to feed a main circuit and an auxiliary circuit from one drive.
• Geared shaft (R) at the drive end - positive connection for clockwise operation.
• Swivel angle and pressure control integrated - the analog command value is enough, an external controller is dropped.
• 24 VDC through a 12-pole connector (11 + PE) to EN 175201-804 - one plug for power and signal.
• 27.5 kg with FKM seals - matched to hydraulic fluid HLP on an ISO 2-hole flange.

Technical data

Applications

The version pays off wherever a flushing, cooling or pilot oil pump has to run beside the controlled main circuit, for example on test rigs and forming lines. Because both pumps hang on the same motor, a second bell housing and its alignment work disappear. The through-drive changes nothing about the control function, and master and slave operation stays available.
