What are Fox Liquid Eductors?
Fox Liquid Eductors are venturi jet pumps that use liquid to create vacuum to mix, blend, or dilute other liquids, dry solids, or gasses into a liquid stream. They are used to replace or eliminate pumps when simple, ultra-reliable liquid mixing is required. They are sometimes referred to as eductor pumps, jet pumps, venturi pumps, or liquid injectors.
Key Features Are:
- No Moving Parts: Fox eductor jet pumps or venturi mixers are very reliable, with no moving parts: no seals, shafts, or bearing requiring maintenance.
- Low Cost Pumping Solution: especially as an alternative to pumps corrosive, gritty, or explosive fluids
- Easy Installation: Eductors are as easy to install as a common “tee” (often called a ‘mixing tee’) and are available with every available end connection, including NPT and BSP threads, flanges, Tri-clamps, tube stub ends
Liquids that can be used to drive a Fox venturi jet pump:
- Water, Seawater or DI Water
- Hydraulic Oil
- Gasoline, jet fuel, biodiesel
- Refrigerants such as R134a
- Orange juice, milk, beverages
Liquid Eductors
Liquid eductors use motive water or other liquids to pump, dilute, mix, or blend other liquids – Pumping and Mixing Liquids.
Pumping Gasses or Vapors with Liquid Eductors
Fox Liquid eductors can create vacuum that can be used to pump, vent, or exhaust gasses, such as the headspace of tanks and vessels with hydrocarbons. Special venturi designs are particularly effective for ozonation and oxygenation of wastewater – Venting/Exhausting Gasses with Liquid Eductors.
Fox Solids Mixing, Slurry Eductors for Blending Liquids & Solids
These eductors are used to mix or blend solids into solutions or slurries – Slurry Eductors
Fox Mini-Eductors for liquid flow rates below 3 GPM
Fox Mini-eductors are 1/4” eductors used for small liquid blending, such as acid dilution, and vacuum applications. They are often used to scavenge fuel or hydraulic oil leaks and sumps in vehicles and engines. They are in stock at Fox in 316 ss, Teflon (PTFE,) CPVC, Monel, and Hastelloy – Mini-Eductors

- Sand & Mud Eductors
Fox recently supplied sand & mud eductor to an environmental remediation contractor. This sand and mud venturi jet pump was dropped down through 25 ft of six inch ID pipe to suck up contaminated sludge and mud at the bottom of a well. Both the motive water line, which drives the eductor, and the eductor discharge pipe, which sends the sludge to the surface, slipped though the 6 inch pipe dropleg. Most importantly, the bottom of the eductor is equipped with downward directed jets that stir up and fluidize the sand and sludge that must be sucked into the eductor and sent to the surface for disposal. A similar installation made at the Playas Hydroelectric Plant in Antioquia Colombia operates so successfully that Fox is now discussing similar eductors for another project in Colombia.
- Another chip manufacturer orders TFE lined eductors for acid dilution
Fox Teflon lined liquid/liquid eductors, manufactured using machined TFE internals and TFE lined, stainless fittings, are installed at more semiconductor manufacturing plants in Asia, EU and USA, in sulfuric acid dilution applications.
