The suction medium of an ejector can be liquids, gasses, solids or a mixture hereof. Basically, the suction medium of an ejector may consist of any fluid up to a certain viscosity level or minor solids.
Many applications exist for ejectors, where a liquid needs to be pumped, a gas needs to be compressed or a vacuum needs to be created using either liquid or gas as the motive fluid. Our homepage section News in Brief shows a variety of examples of the use of ejectors in the industry.
The ejector is able to handle close to every type of suction liquid with the only limitation being very high viscosity fluids. Examples hereof are fluids from regular water to fluids such as oil, fuel or sewage.
Just as for liquids the ejector is also very versatile when it comes to the type of gasses suitable for the use as suction medium. The ejector is able to handle everything from regular air to gasses such as steam, natural gas, smoke or dust.
The maximum tolerable particle size of the suction medium varies with the size and type of ejector. A small ejector tolerates fine particles such as sand, powder or granulate whereas a larger ejector tolerates larger particles such as sewage waste or
gravel. At Ellehammer we have a type of ejectors developed especially for handling suction mediums containing large particles. For more information about handling of large particles please contact firstname.lastname@example.org.
The ejector can be made in a variety of different materials. The most common materials include stainless steel, carbon steel, cast iron, bronze and alu-bronze. Other materials, e.g. plastic, are available upon request.
