Air Jet Syphons

Air or Gas Jet Syphons operate on the jet principle utilising the energy of a gas under pressure to pump liquids and handle solids. In operation syphons use the kinetic energy of motive gas to entrain another liquid or slurry, and then discharge the mixture against a head or counter pressure.

Unlike Steam Jet Syphons, consideration must be given to the motive gas used as gases that will not readily condense in to the suction liquid can limit the operating envelope. However practically any source of gas can be used to operate a Jet Syphon, such as bottled Nitrogen or Argon, or compressed air. This can give greater felxibility if your sites motive supply resources are limited or the installation is in remote location.

Typically uses of Air or Gas Jet Syphons are:

• Sampling liquids or granular solids when the suction fluid must not be contaminated
• Intermittent pumping of liquids from tanks, pits, sumps and bunds

Air Jet Syphons consist of three basic components, namely a converging nozzle, a diffuser (or venturi) , and a body to hold these parts in their relative positions and to provide a suction (or mixing) chamber. In addition, they can be equipped with accessories such as regulating spindles, snap valves and floats to control operation.

Syphons offer numerous advantages over conventional pumps, within the syphon there are no moving parts to wear or break and therefore no parts to require extensive maintenance. Since the syphon is small in relation to the work it does, the unit cost is correspondingly low. Syphons are easy to install and they may be located in remote and inaccessible places without requiring constant attention.

No other pumping & mixing device offers all these outstanding features:

• Low Cost - Units are small in relation to the work they do and cost is correspondingly low.
• Self Priming - Syphons are self-priming. They operate equally well in continuous or intermittent service.
• No Moving Parts - Syphons are exceedingly simple and reliable. There are no moving parts to wear or break in a basic syphon. They only require periodic inspection and maintenance.
• Corrosion and Erosion Resistant - Because they can be made of practically any workable material, or coated with corrosion-resistant materials, syphons can be made highly resistant to the actions of the liquids handled or the environment in which located.
• Safe - Syphons can be used in hazardous locations where electrically operated alternates would require explosion proofing at considerable cost.
• Versitile - Various piping arrangements permit adapting to environmental conditions. Syphons of various types can handle granular solids, semi-solids, and slurries without contamination.
• Automatically Controlled - Units can be adapted for automatic control by means of a pressure liquid regulating spindle or a snap-valve and float arrangement.
• Perform Double Duty - Syphons can mix motive and suction liquids intimately while pumping against a counter pressure.
• Easy to Install - Connections can be made to suit your piping requirements. Little space is required to accommodate units and they are normally so light in weight they can be supported by the piping to which they are attached.
