Steam Jet Syphons

Jet Syphons use steam or other gas as the motive force to pump, heat and mix liquids and handle slurries and granular solids.
Jet Syphons use steam or other gas as the motive force to pump, heat and mix liquids and handle slurries and granular solids. In some cases they can be made to operate with air to pump liquids. These units consist of an expanding nozzle, diffuser and body as shown on the illustration. Steam issues from the nozzle and creates a suction on the body. The suction material is drawn up and entrained by the motive fluid and is discharged against a backpressure.


    Syphons require no priming and can be used in either continuous or intermittent operation.
    Since the basic syphon has no moving parts to wear or break, only periodic inspection is required.
    Because they can be made from most materials or coated with corrosion resistant materials, syphons can be made resistant to the corrosive effects of the liquids handled and the environment. These units are furnished in materials such as: ductile iron, bronze, steel, stainless steel, aluminum, PVC, FRP, Haveg, Teflon, Kynar, and polypropylene to name just a few.
    Units can be adapted for automatic operation by means of a regulating spindle or a snap valve and float arrangement.
    Syphons can be used in hazardous locations where electrically operated alternatives would require expensive explosion-proofing.
    Either threaded or flanged connections are available. Units are compact, relatively light and can be adapted to a variety of piping configurations.
    Water jet syphons are inexpensive in relation to the work they do.
    Syphons are well adapted to processes where heating is required as well as pumping, since the use of steam involves condensation in liquid with an increase in temperature resulting.
  • Intermittent pumping of liquids from tanks and pits
  • Supplying heated water to the jackets of stills and graining bowls
  • Removing liquid from pickling baths
  • Condensing and Mixing Ammonia
  • Pumping Sludge Without Clogging
  • Intermittent Operation
  • Pipeline Heater
Other applications include:
extracting chemicals in reaction chambers, moving powdered material or material in powdered form, filling and emptying gas holder tanks, handling soap solutions in textile plants, pumping sugar juice and various liquids in canning plants, pumping filtrate from vacuum vessels and condensate from surface condensers.
