How many EDP hydraulic pumps are on the CRJ-700?

Explanation:
The main idea is that the CRJ-700 uses two independent hydraulic systems, each powered by its own engine-driven pump located on the engine’s accessory gearbox. Because there is one engine-driven pump per system, there are two EDP hydraulic pumps in total. This arrangement provides redundancy so hydraulic power can be maintained if one engine or pump isn’t available. (There are electric backup pumps as well, but they’re not counted as EDPs.)
