Different pipeline pumps are used in different scenarios, and therefore differ in their usage between low-inlet, high-outlet, and high-inlet, low-outlet pumps.
Low-inlet, high-outlet pumps are suitable for transporting liquids from a low location to a higher location, far away from the original location. On the other hand, high-inlet, low-outlet pumps are suitable for transporting liquids from a higher location, far away from the original location, to a lower location.
