How is the ACW pump powered?

Explanation:
The pump is powered electrically. It runs on alternating current supplied by an ACW generator, so it operates from the aircraft’s electrical system rather than from bleed air or hydraulics or from manual input. This electrical drive allows controlled, autonomous operation and easy integration with cockpit power management. Pneumatic power would require bleed air sources, which this system does not rely on. Hydraulic power would need a dedicated hydraulic drive, which is not the case here. Manual operation would require crew intervention, which isn’t how this pump is designed to function.
