Radial Eductor

All Radial Eductor models require somewhere between 92 -185 feet of head (40 – 80 PSI with fresh water) for optimum performance, and effective operation can often be achieved with 75 feet of head.

• Model RE2000 needs about 135 – 192 GPM (30.6 m3/hr – 43.6 m3/hr) of flow.
• Model RE1500 needs about 69 – 100 GPM (15.6 m3/hr - 22.7 m3/hr) of flow.
• Model RE1000 needs about 45 – 65 GPM (10.2 m3/hr – 14.7 m3/hr.) of flow.

Radial Eductors are High-volume, Low-pressure system components and they are rated to a maximum pressure of 150 PSI and typically require higher volumes of motive flow for operation.

Radial Eductors are constructed of a specific composition of molded polyurethane that is highly resistant to abrasion by solids and erosion by many different chemicals. In applications with highly abrasive, solids laden fluids, such as drilling mud, the urethane composition used in the Radial Eductor wears at a rate of 7 to 8 times slower than steel.

The operating temperature limit is -200F (-28.80C) to 1500F (650C.) The standard urethane construction material has a maximum temperature limit of 1600F (710C,) but the eductors should not be operated above the operating temperature for extended periods of time because the urethane will soften and deform.

The standard version of the Radial Eductor is molded out of urethane. Standard Radial Eductors constructed in other materials besides urethane are not offered. Consideration may be given to offering eductors in alternative materials if the volume of units needed justify engineering and production efforts.

The flow and pressure required to operate Radial Eductors should be delivered by centrifugal pumps, but positive displacement or other types of pumps that provide steady, constant flow can be used as well.

The motive fluid pumped through the Radial Eductors may be drawn out of the vessel and recirculated back into the same vessel through the eductors; or it may come from a secondary source, such as another vessel or reservoir.

Yes. They can be used in conjunction with mechanical agitators to prevent settling of solids in the corners of rectangular tanks, or they can be used without mechanical agitators as the primary means of agitation.

No. Vortex Ventures does not supply the manifold piping for mounting the Radial Eductors and energizing them with motive flow. However, Vortex Ventures can review the application parameters and recommend the optimal configuration for the manifold and the positioning of the eductors.

The total discharge flow is the total rate of inlet plus induced fluid flow that will pass through all the eductors inside a vessel. This is a quantifiable measure that only partially indicates how efficient the tank mixing eductor system is, but it only takes into consideration the fluid passing through the eductors and does not account for the additional fluid entrainment and displacement of the discharge plumes. The turnover rate of a mechanical agitator is determined by the displacement of the agitator blades as they rotate in the vessel.

The turnover ratio of any tank mixing eductor is commercially expressed as a ratio of inlet, motive flow to the volume of fluid induced by the motive jet and only accounts for the fluid that passes through the eductor. This value only partially indicates the total effectiveness of the eductor and the “true” turnover rate of the entire fluid volume of a vessel encompasses this value, as well as the total fluid movement created by the eductor plumes. Given the complexities of fluid dynamics and multiple variables that change from application to application, this “true” turnover rate is very difficult to quantify. The “true” turnover rate is essential for effective tank agitation, and it is maximized by the strong rotational energy of the Radial Eductor plume, which entrains and displaces a greater volume of fluid than paddle agitators and other tank eductors.
