eductor

There was no eductor (a type of water pump).

A water dredge or water eductor may be used for the same purpose.

A water eductor or water dredge is an eductor-jet pump-based tool used by underwater archaeologists to remove sediments from an underwater archaeological site.

Depending on the specific application, an injector takes the form of an eductor-jet pump, a water eductor, a vacuum ejector, a steam-jet ejector, or an aspirator.

A BHM tool usually has (down-up): an eductor (waterjet pump) section, a hydromonitor section, an extension section and a hub, connecting it all to a drill pipe string.

Formerly known as Mindanao Institute of Technology (MIT) founded by late Bai Hadja Fatima Matabay Plang, an eductor and philanthropist.

A venturi siphon, also known as an eductor, is essentially a venturi which is designed to greatly speed up the fluid flowing in a pipe such that an inlet port located at the throat of the venturi can be used to siphon another fluid.

They are used onboard many ships to pump out flooded compartments: in the event of an accident, seawater is pumped to the eductor and forced through a jet, and any fluid at the inlet of the eductor is carried along to the outlet and up and out of the compartment.
