Two specification sheets cannot be compared reliably when their units, test media, working-head designs, and operating duties differ. A larger number may represent a different model scale or reference condition rather than better performance for the intended process. The engineering brief for an inline high shear mixer first defines the required dispersion, homogenization, crushing, blending, or mixing result.
Material viscosity, solids content, temperature, and acceptable number of passes should be recorded alongside that target. Only then can power, rotational speed, stages, connection size, and maximum flow be placed on common rows. A disciplined inline shear mixer comparison aligns the duty point before it ranks the data.
Start with the Working Head and Number of Stages
The working head defines where the material encounters the principal mechanical action. Geometry and clearance influence how a stream passes through the shear zone, while single-stage and multi-stage arrangements change the number or sequence of processing regions.
An inline high shear mixer should therefore be classified by head design and stage configuration before its motor figures are compared. The term inline shear mixer covers equipment that may use different shear structures, so identical power ratings do not guarantee an identical material path.
The comparison should also note whether the process expects one pass or recirculation through the system. Engineers should record the intended function beside each configuration rather than treating stage count as an isolated indicator of quality.
Read Power and Speed as a Pair
Motor power describes rated drive capacity, while rotational speed describes how fast the rotating element operates; neither figure alone states the process result. Model size, head geometry, load, and material behavior affect how those inputs translate into operation.
FLUKO’s FD1/SG range illustrates the relationship within one family: the FD1/40SG is rated at 0.75 kW and 9,000 rpm, whereas the FD1/150SG is rated at 22 kW and 2,900 rpm. The smaller inline high shear mixer runs faster, but the larger unit serves a different scale.
Available electrical supply and the expected load should be reviewed before either rating becomes an installation decision. An inline shear mixer table should keep model, power, speed, and head design on the same row so engineers do not equate rpm with total processing capability.
Compare Flow Only under a Defined Reference Condition
Maximum flow is meaningful when the test medium and operating basis are known. FLUKO publishes maximum water-flow values of 3.4 m³/h for the FD1/40SG and 50 m³/h for the FD1/150SG. Water is a reference, not a prediction for every viscosity, solids loading, or target fineness.
The duty flow for an inline high shear mixer may need to be lower when the material requires more intense or repeated treatment. Required throughput should also be expressed at the same time basis and under the same production assumptions across candidates.
A side-by-side inline shear mixer review should therefore separate published maximum water flow from the project’s required process flow and ask how the intended formulation changes the operating point.
Include Connections Cleanability and Line Integration
Mechanical fit can eliminate an otherwise suitable model from a shortlist. Connection size affects compatibility with existing piping, and installation space influences how the unit can be positioned and serviced. Cleanability matters where product changeover or sanitary processing sets the operating standard.
Maintenance access, drainage, and the orientation of adjacent piping may also influence the usable layout. FLUKO’s FD1/SG series uses a narrow-gap working head, supports dispersion, homogenization, crushing, blending, and mixing, and meets CIP/SIP cleanliness standards.
These features add application context to the inline high shear mixer data. FLUKO also describes its FDX inline shear mixer design as compact, stable, simple to install, and easy to integrate into production lines.
Use Model Range to Check Scale Fit
A product family should cover the required duty without forcing an engineer to extrapolate far beyond published data. FLUKO’s FDX range offers different shear configurations, begins at 0.75 kW, and extends in its larger single-stage models to 110 kW and a maximum water flow of 125 m³/h; three-stage configurations are also available.
Those figures show breadth, but the selected inline high shear mixer still has to match the actual material and required result. Scale changes can alter circulation, residence conditions, and the practical relationship between throughput and treatment intensity.
Comparing an inline shear mixer at the correct scale means checking the nearest model data, configuration, connection, and flow basis together rather than assuming that every intermediate duty behaves linearly.
Turn the Specification Table into an Engineering Shortlist
The final comparison should normalize function, head design, number of stages, motor power, rotational speed, connection size, maximum water flow, reference medium, cleanability, and installation needs.
Engineers can then identify missing data and request confirmation for the real process conditions. A candidate inline high shear mixer belongs on the shortlist only if its combined specifications support the target duty. A suitable inline shear mixer is better identified by how well its combined operating data matches the target duty than by the largest number in any single column.
