Steam Jet Syphon

Principle of Operation

Fig. 217 and Fig. 219 Steam Jet Syphons are designed for liquid pumping and mixing operations and for the handling of some solids.  Steam, air or gas under pressure is used to pump, mix liquids and handle solids. Fig. 217 and Fig. 219 Steam Jet Syphons can be used for the handling of corrosive or abrasive liquids and solids because of their design simplicity, absence of moving parts, and can be made from any machineable material.

Steam Jet Syphons are especially well suited for processes where heating is required in addition to pumping since the pumping is accomplished for the cost of the heating.

Fig. 2175 Automatic Steam Jet Syphons are used to pump out sumps (pits, tanks, etc.) where liquid accumulates slowly but must be evacuated when it reaches a predetermined level. Operation of the Fig. 2175 Automatic Steam Jet Syphon requires no electrical connections or external power other than motive fluid.


Fig. 217 and Fig. 219 Steam Jet Syphons offer numerous advantages. Within the syphon, there are no moving parts to wear or break, and thus nothing to require extensive maintenance. Since the syphon is small in relation to the work it does, the cost is correspondingly low. Easy to install, they may be located in remote and inaccessible places without requiring constant attention.

The Fig. 2175 Automatic Steam Jet Syphon is self-operated and requires no electrical connections.  The snap-action valve and ball float are the only moving parts.  Special Automatic Syphons can be made from any other jet syphon
