What component can be used for water wash?

Explanation:
Water wash relies on delivering wash fluid under pressure into the compressor to clean the blades and passages. The component that provides the necessary pressure and flow to move the wash fluid through the lines is the water wash pump. It pumps the wash solution to the wash manifold and spray nozzles so the fluid can reach the compressor internals. The other items have different roles: a pneumatic starter supplies starting air, a fuel injector introduces fuel, and a coolant spray nozzle is used for cooling, not for delivering wash fluid.
