Selection Guide
For each application, the designer must first determine the number of mixing sections required to achieve a complete mix. The guidelines below are based upon the Reynolds Number of your system. Also included are tables with some general application guidelines. Next, the designer should select a diameter and/or a construction that will give the desired mixing performance without exceeding your system’s maximum allowable pressure drop (see item 3 below).
1. Calculate the Reynolds Number. Use the diameter given in the charts. If both inside and outside diameters are supplied, use the inside diameter

3. Determine the Pressure Drop
Laminar Flow:
Reynolds Number < 500 DP = Q x MU x L Turbulent Flow:
Reynolds Number > 500 DP = Q2 x S x T
Note: If the pressure drop across the mixer exceeds its maximum rating, a modular mixer is required. For example, if a 24-element FMX8300 mixer is required and the pressure drop exceeds the 250 psi rating, we recommend coupling two 12-element mixers in series.

MIXING ELEMENTS
FMX7100/
8100 Series
The FMX7100 and FMX8100 series mixing elements are injection molded in one operation to ensure low cost with excellent quality. The FMX7100 series are specifically designed for low viscosity applications. The FMX8100 plastic spiral elements were developed for adhesive and sealant and other high viscosity mixing applications. The leading and trailing edges of the FMX8000 mixers are “knife edged” so that the unit flushes clean with less solvent—no flat leading edges to accumulate material.

Polyacetal is completely inert to most common solvents, such as MEK acetone, and methylene chloride for use in the Adhesive and Insulation industries. Its maximum service temperature is 250°F. Polyacetal is not recommended for service with bases or acids. Polypropylene has

FMX7200 Series
The FMX7200 Series is an effective answer to your mixing requirements. Operating in-line, with no moving parts, these mixers blend and disperse treatment chemicals into waste water streams. Compared to competitive mixers, its unique baffling design ensures complete mixing in a shorter length and lower pressure drop.
The FMX7200 Series is easily installed in new or existing process lines. They are available in pipe sizes from ³⁄₄ to 2" diameter. Construction materials include PVC, and CPVC.
FMX7200 Series mixers are specially designed for waste water treatment, mixing additives, pH control, and polyelectrolyte dilution. These all-plastic mixers combine PVC or CPVC pipe with polypropylene internals. Certain sizes feature clipped sections, which eliminate sharp crevices where material can accumulate and plug up the mixer. Polypropylene has excellent chemical resistance to most acids and bases. The maximum service temperature of a standard FMX7200 Series mixer is 60°C (140°F) with PVC housing, 82°C (180°F) with CPVC housing.

OMEGA® FMX7200 Series mixers are designed for efficient turbulent-flow mixing at low pressure drop. Ideal for admixing water/ wastewater treatment chemicals, polymer dilution, and other low-viscosity applications. Mixing elements consist of a series of polypropylene baffles, and are mounted in a PVC housing with FNPT ends. CPVC and clear PVC housings available.

FMX8400 Series
FMX8400 Series pipe mixers feature 304 SS piping (schedule 40 nominal) with 316 SS elements. For routine maintenance, the elements can be pushed out and cleaned.
The leading and trailing edges of the mixers are “knife edged” to flush clean with less solvent, having no flat leading edges to accumulate material.
The FMX8400 Series consists of effective motionless mixers. When combined with metering pumps, these mixers replace expensive treatment tanks and dynamic mixers. Consider these advantages: zero maintenance, low cost, easy installation, and low energy consumption.
Typical applications include laminar or turbulent blending, liquid/gas contacting, and enhanced heat transfer. The mixing process is modular: the more difficult the application, the greater the number of elements required.

OMEGA FMX8400 Series mixers offer efficient mixing of low or high viscosity fluids at low pressure drop. Also ideal for two-phase (gas-liquid) mixing and blending of gases. Elements consist of a series of left and right helixes fabricated from 316 SS. 304 SS housing is corrosion-resistant, designed for high pressure and high temperature service. MNPT ends ensure easy installation.

STAINLESS TUBE AND SPIRAL SANITARY MIXERS
FMX9600 Series
The FMX9600 Series spiral mixers are designed for high-pressure applications such as two component adhesives and sealants. The mixers consist of a series of left and right hand spiral elements which have been “edge-sealed” into a tube. The spiral tube mixer is available in four diameters and with 21 to 32 elements. The elements have been nicrobrazed along their complete length and cannot be removed from the tube. Consider the advantages of this all-stainless steel assembly: the moderate price offers significant savings over competitive mixers, the contour of the elements ensures that the mixer flushes clean with less solvent, and the tube mixers are manufactured with heavy walled tubing, which resists warpage during furnace cleaning and increases the life of the mixer.
