Plastic Tank Nozzles (Eductors)

Plastic Tank EductorsPlastic Tank Nozzles are available in PPL (Glass Reinforced Polypropylene) and PVDF (KYNAR®). Eductor circulation ratio of supply to discharge is 1:5

Tank Nozzles are designed for "in-tank" applications. The TLM operates on the principle of flow dynamics pressurized fluid is accelerated through the nozzle to become a high velocity stream that entrains tank contents and intimately mixes with them. This combined stream exits the TLM at a high velocity creating a flow field capable of causing additional agitation and mixing the tank contents.   

 

The Tank Nozzles' motive fluid may come from two sources. The tank liquid may be re-circulated through the eductor via an external pump or a secondary fluid may be introduced into the tank. Gases, as well as liquids, are used as the secondary fluid. Aeration and gas dispersion for chemical reactions are common uses of gas motive systems. Liquids are typically additives to be mixed with or to dilute the tank contents.

Polypropylene (PPL) a polymer prepared catalytically from propylene which differs from HDPE by having an isostatic replacement of a hydrogen atom by a methyl group on alternate carbon atoms in the main chain. Although largely unreactive chemically the presence of the methyl groups makes  Polypropylene slightly more susceptible to attack by strong oxidizing agents than HDPE. A major advantage is Polypropylene's higher temperature resistance.

 

Excellent resistance (no attack) to dilute and concentrated Acids, Alcohols, Bases and Mineral Oils

Good resistance (minor attack) to Aldehydes, Esters, Aliphatic Hydrocarbons, Ketones and Vegetable Oils

Limited resistance (moderate attack and suitable for short term use only) to Aromatic and Halogenated Hydrocarbons and Oxidizing Agents.

KYNAR® (PVDF) is a high molecular weight thermoplastic polymer with excellent chemical inertness. It is highly resistant to oxidizing agents and halogens and is almost completely resistant to allphatic, aromatics, alcohols, acids and chlorinated solvents. It is resistant to most acids and bases.  Mechanically strong. High dielectric strength. Thermally stable. Resistant to low temperatures. Stable to ultraviolet and extreme weather conditions. Self-extinguishing and non-toxic.
