EJECT-ELL

EJECT-ELL Ejector

Ejectors operate on the principle that a high velocity flow through a nozzle will create a pressure drop in the area around the nozzle discharge. The resulting vacuum will induce flow into the secondary inlet of the ejector. Applications include: exhausting, agitating, aerating, circulating, pumping and mixing

Features

  • No moving parts
  • Can be used with water or steam pressure
  • Submersible
  • Available in cast iron or bronze
 

How a EJECT, EJECT-ELL & EJECT-LM Works

Using water, steam or air pressure as the motive force, ejectors operate on the principle that a high velocity flow through a nozzle will create a pressure drop in the area around the nozzle discharge. The resulting vacuum will induce flow into the secondary inlet of the ejector.

Ejectors Shown Pumping Liquid

EJECT-ELL is used for the evacuation of autoclaves and other vessels using water as the motive fluid. See performance charts on the following pages.

Product Overview
Watson McDaniel Ejectors perform a variety of functions depending upon the application and motive fluid (steam or water) used. See performance charts on the following pages. Applications include: exhausting, agitating, aerating, circulating, pumping and mixing.

Installation and Maintenance

It is always desirable to keep the Ejector as close to the actual liquid being pumped as possible. The maximum height the liquid can be pumped depends upon the pressure of the “motive” liquid or steam available. Please refer to the capacity graphs for maximum flow rates and maximum achievable heads.

The maximum height that water or any liquid with a specific gravity of 1 can be lifted is 25 feet. Increases in the temperature of the liquid being lifted will cause this maximum height to decrease. Pumping liquids in excess of 130°F is not recommended. Please consult factory with any specific application.

Sample Specification
Ejectors shall be constructed from bronze or cast iron. Units shall be capable of using steam, water or air as a motive force.
