All ejectors are engineered and manufactured in Denmark and fulfill all demands of the respective class societies.Ĭlick on below links to download brochure or case documentation in pdf-format. Due to this, the ejectors velocity can go up to 2 mach (2000 feet/sec).

Suitable as a portable ‘vacuum cleaner’Įllehammer's wide range of ejectors are as standard, manufactured with a body in bronze and on request, can be produced in materials such as aluminum bronze, cast iron and stainless steel. Where the eductor uses water (liquid) as a motive medium, the ejector uses steam or air.

Eliminates risks of fire/explosion as no moving parts.

Suitable on locations with limited access.

Allows unobstructed transport of impurities in suction media Eductors and Ejectors have the same functionality, in that they both use a motive fluid, to produce some level of vacuum.

There are several advantages for using an ejector for a specific application. A well dimensioned ejector has a big influence on the piping system and power requirements of the driving pump. Steam ejectors (also known as Ejectors, Eductors, Jet Pumps, Velocity Spools or simply SJPs) are devices that use the energy from a high-pressure fluid to. Taking these parameters into account allows us to determine the most effective and best suitable ejector for your application. Rotary airlocks can be replaced by venturi eductors to. When dimensioning an ejector, certain parameters are taken into account including amongst others: pipe sizing, the amount of liquid to be transported and capacity of the driving pump. The Ejector sprays high speed steam, gas, or liquid through a nozzle and can produce vacuum stages. The power of the ejector is in its detail and design. Our sewage ejectors may also be used to transport minerals or granulate mixed with water. Sewage applications most often involves the transportation of black water and grey water. The most common applications being ballast stripping, bilge and sewage applications.īallast stripping may involve discharging through a ballast water treatment system which puts additional requirements to the ejector.īilge applications typically includes removing liquid and condensate from the chain locker, cofferdam, bosun store or engine room etc. Refer to the simplified Bernoulli’s equation below for an in compressible flow. Onboard the vessels the ejector serves a variety of different applications. It states that an increase in the speed of a fluid occurs simultaneously with a reduction in pressure.

The system works by circulating high pressure water which is fed from a. The distilled water jet ejector withdraws water vapor from the top of the. Eductors use air within the wells to produce a vacuum to draw water out of the soil. The impure water jet ejector withdraws water from the bottom of the evaporator. Ejectors are broadly used onboard almost every kind of vessel including ferries, fishing and cruise vessels and onboard carrier vessels to name a few. Like the deepwell systems, the eductor (or ejector) system is based on wells that are drilled to lower the groundwater level to provide stable working conditions. Jet Syphons use steam or other gas as the motive force to pump, heat and mix liquids and handle slurries and granular solids. No maintenance is required, and wear & tear is at a very minimum. Our Sludge Eductor and Slurry Eductor handling units are supplied as standalone Eductor units as well as full-fledged skid mounted installations.The Ejector - Ingenious in its simplicity The power of the ejector is in its detail and design.Īn ejector, also known as an eductor or a jet pump, is a piece of precision engineering without any moving parts. Our material selection plays an important role in ensuring long operating life in the face of abrasive conditions The main function of the eductor is compression. The diameter of the eductor throat is larger than that of ejectors. Ejectors simply suck the excess volume of fluid to maintain system pressure. The flow friendly and non-clogging nature of Eductor design make our Eductors the perfect match for your sludge and slurry handling requirements. Eductors usually have a high compression ratio as compared to ejectors. Our experience with Eductor Technology enables us to derive solutions for even the most viscous slurries applications. Fox Venturi Jet Ejectors (also called eductors, venturi jets, aspirators, jet mixers, jet pumps) use any gas such as air, nitrogen, steam, nat gas, etc. We manufacture and supply specialized Eductor solutions for Sludge and Slurry Handling. 1 is a photo of an installed ejector at a CVDU. Eductors being static devices do not create maintenance and reliability problems when used for Slurry handling. Tables 1 and 2 are troubleshooting guides to ejector and condenser problems in vacuum ejector systems. Sludge and Slurry pumping are demanding applications which put a strain on the pumping setup. Due to their name similarity and with both pumps looking the same, ejector and eductor pumps are often mistaken for one another. Slurry Eductor | Sludge Eductor | Solids Eductor Difference between ejector and eductor pump.
