Pumpenregelsystem SYDFEE-2X/018R-PSC12N00-0000-C0B0VX1 - Bosch Rexroth R901158404

A hydraulic power unit that sets its flow with a throttle turns the unused power into heat and loads the oil cooler. The SYDFEE-2X/018R-PSC12N00-0000-C0B0VX1 pump control system works with a variable pump of size 18 cm³ instead, supplying up to 59 l/min at an operating pressure of 280 bar while the swivel angle is corrected electronically.

Key benefits

• Two control loops in one unit - the on-board electronics close both the swivel angle loop and the pressure loop, so a separate amplifier cabinet becomes unnecessary.
• 59 l/min from 18 cm³ displacement - covers medium sized power units without a second pump running alongside.
• 280 bar operating pressure - in this version the preload valve is rated 200 bar to feed the control circuit.
• Analog command value on a 24 VDC supply - both share the 12-pole connector (11 + PE) to EN 175201-804.
• Geared shaft (S) at the drive end - positive engagement, laid out for clockwise rotation.
• 18.8 kg on an ISO 2-hole flange - master and slave operation of several units belongs to the functional scope.

Applications

Typical installations are power units on presses, injection moulding machines and test rigs where pressure and flow swing widely over the cycle. Because the pump delivers only what the actuator draws, power loss stays low at part load. The FKM seals match hydraulic fluid HLP. The unit is built without a through-drive, so it suits single pump operation on one motor.
