ejector pump

Ejector pump efficiency depends on the length-to-diameter ratio of the exhaust chimney.

A compressed air driven ejector pump provides vacuum conditions in the test section vessel during test runs.

He said he wanted to install an ejector pump to force the excess sewage into the Riverside Drive sewer line.

It sought to "augment" available thrust by injecting the engine exhaust into an ejector pump in the fuselage.

Although such ejector pumps waste water and are relatively inefficient, they have the advantage of having no moving parts and offer the utmost in reliability.

An ejector pump can be used for rapid evacuation of the air inside an autoclave that is to be pressurized with inert gas.

Eight fire engines were despatched to the harbour in Leith, where they are using ejector pumps to remove the water.

There are more than 325 drainage systems or so-called pneumatic ejector pumps in the subways that link underground toilets to the sewers.

Operation ceased in 1972, when the only other Schone Ejector pumps in the country were those under the houses of parliament.

The ejector pump has produced test section pressures as low as 4.5 kPa (0.65 psia) without the arc heater running.

One can also use an ejector pump that uses an ordinary garden hose to supply high pressure water and another garden hose to carry the water away.

The theater sustained 14 ft. of water, which damaged the motor control center, orchestra lifts, heating and air-conditioning controls, sewerage ejector pumps and other structural components.

Rockwell International built, and then abandoned, the Rockwell XFV-12 supersonic fighter which had an unusual wing which opened up like window blinds to create an ejector pump for vertical flight.

In addition, the rotating exhaust acted as an effective wall at the outer edge of the engine base, and the entire base area effectively is pumped down below ambient due to ejector pump effect, creating an effective suction cup at the bottom in atmosphere.
