TANK MIXING EDUCTORS : TYPE 468
APPLICATION
Tank Mixing Eductors are used in applications requiring agitation or mixing in a tank, pit or sump. They are static mixers which can be used to mix and blend different liquids in a tank or to simply maintain a homogeneous mixture. Tank mixing eductors reduce the size of the circulating pump required in many mixing applications by entraining the tank contents. Tank mixing eductors can be used to assist in dissolving powders in mixtures or to keep solid particles in suspension. They can often replace motor driven mechanical agitators and thereby avoid the maintenance associated with mechanical devices. They can also be used with air or other gases or motive in aeration and gas dispersion applications.
When steam is used as a motive, the tank mixer becomes an effective heater.
OPERATION / PERFORMANCE
Motive liquid exits the motive nozzle at a high velocity which entrain the surrounding tank liquid. The mixture then passes through the mixing venture which enables the liquid to overcome the static height of liquid in the tank above the eductor(s). A circulating flow pattern is established.
Entrainment ratios of 3 to 1 are normally achieved. For every gallon of motive liquid, 3 gallons of suction liquid are entrained by the eductor.
INSTALLATION
Feed manifold types can be single long headers, crosses, header and multi-lateral or hub and lateral. Manifolds are ftted with an even distribution of strategically placed eductors to encourage complete tank coverage. Eductor flow patterns should intersect to achieve the best results and should be directed at stagnant tank corners.
CONSTRUCTION
Tank Mixing Eductors consist of a one piece body and venture. They are available in almost any material including Steel., Stainless Steel , Monel, Hastelloy, Titanium, PVC, CPVC, Kynar, Teflon, and fiberglass depending on the application. Connections are typically flanged or threaded, but can be supplied with special connections.
