Steam jet ejectors are used in the chemical, petrochemical, pulp and paper, food, power, steel and allied industries in connection with such operations as filtration, distillation, absorption, mixing, vacuum packaging, freeze drying, flash cooling, dehydrating and degassing to name just a few.
Schutte & Koerting manufactures a complete line of Steam Jet Ejector Vacuum components and systems. Based on the ejector-venturi principle, steam issuing through an expanding nozzle has its pressure energy converted to velocity energy. A vacuum is created, air or gas is entrained and the mixture of gas and steam enters the venturi diffuser where its velocity energy is converted into pressure sufficient to discharge against a predetermined back pressure.
Materials of Construction
Steam jet ejectors are readily available in ductile iron, steel, stainless steel and any alloy such as Monel, Hastelloy, Alloy 20, Titanium, and bronze. This equipment is also available from a wide variety of non metals such as Teflon, Graphite and Haveg.
Steam jet ejectors are used in the chemical, petrochemical, pulp and paper, food, power, steel and allied industries in connection with such operations as filtration, distillation, absorption, mixing, vacuum packaging, freeze drying, flash cooling, dehydrating and degassing to name just a few. They will handle both condensable and non-condensable gases and vapors as well as mixtures of the two. Small amounts of.solids or liquids will not adversely affect performance. All S&K ejectors are computer designed and type-tested to insure reliability.
- Low Cost - Pumps of the ejector type are small in relation to the work they do and their cost is low in comparison with other types of equipment.
- No Moving Parts - These units have no moving parts to adjust or repair.
- Simple, Compact Construction - Nothing could be simpler than a jet vacuum ejector. It consists of an expanding nozzle, a body, and a venturi (or diffuser).
- Reliability - Because of their inherent simplicity, these pumps are reliable. Maintenance requirements are simple and easily accomplished.
- Corrosion/Erosion Resistance - Units can be made in practically any workable material to provide utmost resistance to corrosion and erosion.
- Easy Installation - Relatively light in weight, jet ejectors are easy to install, and typically require no foundations. Even multi-stage units are readily adaptable to existing conditions.
- High Vacuum Performance - Steam jet ejectors can handle air or other gases at suction pressures as low as three microns Hg. abs.
