04 / STATIC MIXERS
Static Mixers
In-line mixing units that blend, disperse or react fluids as they flow through a pipeline — no moving parts, no external power — configured for general, sanitary, laboratory, thermal and high-viscosity duties.
IN-LINE MIXING
How a Static Mixer Works
A static mixer uses a series of fixed internal elements installed inside a pipe or housing to repeatedly divide, redirect and recombine the flow stream. As process fluid moves through the unit, this geometry produces thorough mixing, dispersion or heat exchange without any rotating or externally powered components. Because the elements can be configured for a specific housing type, connection style and process condition, static mixers are applied across a wide range of duties — from general blending to sanitary, laboratory, steam-heating and high-viscosity service.
- No moving parts — mixing occurs as fluid passes the fixed elements, no motor or rotor
- Modular elements — standard 6 per unit, increased or decreased to suit the duty
- Application-specific — housing, connection and materials selected for the process
Applications: mixing and dispersion, chemical reaction, heat exchange, extraction, chemical dosing, water and wastewater treatment, gas–liquid contacting
SELECTION GUIDE
Choosing by Application
| Configuration | Primary application | Housing | Connection |
|---|---|---|---|
| General Purpose | General purpose mixing | Standard pipe | Standard |
| Sanitary / Food-Grade | Sanitary / hygienic processing | Sanitary pipe (ferrule) | IDF joints |
| Laboratory | Laboratory / pilot plant | Glass or acrylic pipe | Standard |
| Steam Injection | Direct steam heating of liquid | Standard pipe | Standard |
| High-Viscosity | High-viscosity liquid processing | Special edge-sealed housing | Standard |
All five use a standard element count of 6 per unit, adjustable to the application. Materials of construction are confirmed per customer specification and process requirement at order stage.
TYPE 01 · GENERAL PURPOSE
General Purpose Mixer
General-purpose mixing configured with a standard pipe and standard connection to suit the application. The baseline static mixer for continuous blending, dispersion and reaction duties across process industries, with the element count adjusted to the mixing requirement.
- Wide range of uses
- Number of elements adjustable to the duty
Applications: mixing, dispersion, heat exchange, chemical reaction, extraction
TYPE 02 · SANITARY / FOOD-GRADE
Sanitary / Food-Grade Mixer
Sanitary / hygienic processing configured with a sanitary pipe (ferrule) housing and IDF joint connections. The sanitary interior finish and easily removable elements allow both clean-in-place (CIP) and disassembled cleaning, making it suitable for food and medical processing.
- Sanitary interior finish
- Elements easily removable
- CIP and disassembled cleaning possible
Applications: foods, beverages, medical products, hygienic and pharmaceutical processing
TYPE 03 · LABORATORY
Laboratory Mixer
Laboratory / pilot-plant configuration with a glass or acrylic pipe and standard connection. The transparent tube lets you observe the mixing status directly, making it ideal for laboratory work, method development and pilot-scale experiments.
- Visible / transparent tube to observe mixing status
Applications: laboratory, pilot-plant experiments, process development
TYPE 04 · STEAM INJECTION
Steam Injection Mixer
Direct steam heating of a liquid, configured with a standard pipe and standard connection plus a steam inlet. Steam is injected straight into the flowing liquid and mixed by the elements for high thermal efficiency with low heat loss, and with minimised noise and vibration compared with open steam sparging.
- Heats liquid by direct steam injection
- Minimised noise and vibration
- High thermal efficiency, low heat loss
Applications: direct liquid heating with steam, process water and slurry heating
TYPE 05 · HIGH-VISCOSITY
High-Viscosity Mixer
High-viscosity liquid processing configured with a special edge-sealed housing. Zero clearance between the housing and the element leaves no unmixed film at the wall, so thick fluids are fully mixed — the configuration for viscous chemical and textile-process streams.
- Zero clearance between housing and element
- Special edge-sealed mixer for viscous fluids
Applications: high-viscosity processes in the chemical and textile industries, polymer and paste blending
Frequently Asked Questions
What is a static mixer and how does it work?
A static mixer is an in-line mixing unit that blends, disperses or reacts fluids as they flow through a pipe — without moving parts or external power. A series of fixed internal elements repeatedly divides, redirects and recombines the flow stream, so that as fluid passes through, the geometry produces thorough mixing, dispersion or heat exchange. Because there is no motor or rotor, it needs no drive power and effectively no maintenance.
Inline mixer vs static mixer — are they the same?
A static mixer is one type of in-line mixer — the motionless kind, with fixed elements and no moving parts. Other in-line mixers are dynamic, using a powered rotor (in-line homogenisers and mixer pumps). If you need continuous mixing in a pipeline with no drive, no maintenance and low running cost, the static mixer is the in-line option; where very high shear is required, a dynamic in-line mixer may be used instead.
How many mixing elements does a static mixer need?
All five configurations here use a standard element count of 6 per unit, which is increased or decreased to suit the mixing duty and flow conditions. More elements give more complete mixing at the cost of a higher pressure drop; the right count depends on the viscosity ratio, flow rates and how tight a blend you need. Send us your process conditions and we will confirm the element count.
Which static mixer configuration should I choose?
Match the housing and connection to the duty: General Purpose (standard pipe) for everyday blending; Sanitary / Food-Grade (ferrule housing, IDF joints, CIP-cleanable) for food and medical processing; Laboratory (glass or acrylic pipe) where you need to see the mixing; Steam Injection (standard pipe) for direct steam heating of a liquid; and High-Viscosity (special edge-sealed housing, zero clearance) for thick chemical and textile-process fluids. See the selection guide above.
What materials and sizes are available?
Housing and element materials of construction are confirmed per customer specification and process requirement at order stage — commonly stainless steel, with glass or acrylic for laboratory units and other alloys or polymers on request. Line size and element count are matched to your pipe and flow. PCX sources static mixers through an international partner network; additional types, sizes and material options are available on request.
