FLUKO F40Z-591-S Inline High-Shear Disperser & Homogenizer

Overview

The FLUKO F40Z-591-S is an inline high-shear disperser and homogenizer engineered for scalable process development and pilot-scale validation in R&D laboratories and quality control environments. Based on the proven rotor-stator principle—where fluid is subjected to intense hydrodynamic shear, cavitation, and turbulent mixing within a precisely engineered gap—the F40Z delivers consistent particle size reduction, droplet breakup, and colloidal stabilization under continuous flow conditions. Its design bridges the gap between benchtop batch processing and full-scale production, enabling users to simulate industrial inline circulation or continuous processing workflows directly in the lab. With a maximum tip speed of 40 m/s and a wide operational speed range (2500–23,500 rpm), the unit generates reproducible shear profiles across varying viscosities (up to 1000 cP) and flow rates (1–30 L/min), supporting robust method transfer from lab to plant.

Key Features

• High-performance brushless motor delivering 1800 W continuous power output with thermal protection and stable torque across the full speed range
• Precision-machined SS316L rotor-stator working head (40DG configuration) optimized for fine dispersion and narrow particle size distribution
• Integrated mechanical seal assembly using silicon carbide (SiC) rotating face and FKM elastomer static components—rated for continuous operation at up to 120 °C
• Modular inline configuration with 18 mm hose-barb inlet/outlet ports, facilitating rapid integration into recirculation loops or continuous flow systems
• Robust SS304 base frame and compact footprint (675 × 200 × 175 mm) designed for stability on standard laboratory benches or mobile carts
• Stepless analog speed control with calibrated dial interface—enabling precise, repeatable setpoint adjustment without digital electronics or software dependency

Sample Compatibility & Compliance

The F40Z-591-S accommodates aqueous, solvent-based, and moderately viscous non-corrosive formulations typical in pharmaceutical emulsion development, cosmetic formulation, battery slurry preparation, and nanomaterial dispersion. All wetted surfaces—including the work chamber, rotor, stator, and shaft—are constructed from electropolished SS316L to ensure corrosion resistance and cleanability per ISO 14644-1 Class 7 (or better) cleanroom-compatible protocols. The mechanical seal meets DIN 24960 and ISO 21049 standards for rotary shaft sealing performance. While not certified for hazardous area use (ATEX/IECEx), the unit complies with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) electromagnetic compatibility requirements. It supports GLP-compliant documentation when paired with external flow meters and temperature sensors traceable to NIST standards.

Software & Data Management

The F40Z-591-S operates as a standalone analog instrument with no embedded firmware, eliminating cybersecurity concerns and ensuring long-term operational continuity without software updates or licensing. Speed is monitored via calibrated mechanical dial indicator—providing direct visual feedback without reliance on digital displays or data logging. For regulated environments requiring audit trails, users may integrate the unit into third-party SCADA or LIMS platforms via external 4–20 mA or 0–10 V analog signals (when coupled with optional speed transducers or flow controllers). All operational parameters—including flow rate, inlet/outlet temperature, and cumulative runtime—can be recorded manually or via connected instrumentation meeting FDA 21 CFR Part 11 requirements for electronic records and signatures.

Applications

• Pharmaceutical: Preparation of nanoemulsions, liposomal suspensions, and polymer nanoparticle dispersions under GMP-aligned process simulation
• Materials Science: Deagglomeration of carbon black, graphene oxide, or metal oxide nanoparticles in solvent or aqueous media
• Food & Beverage: Development of stable oil-in-water emulsions (e.g., dressings, sauces) and protein-fortified beverages with reduced sedimentation
• Adhesives & Coatings: Homogenization of pigment dispersions and rheology modifier incorporation into acrylic or epoxy resins
• Battery Manufacturing: Uniform dispersion of cathode/anode active materials (e.g., NMC, graphite) in PVDF/NMP slurries prior to coating trials

FAQ

Can the F40Z-591-S be used for sterile processing?
No—it lacks steam-in-place (SIP) capability, autoclavable construction, or validated microbial retention seals. It is suitable for aseptic technique-supported operations but not for terminal sterilization cycles.
Is the 40DG work head interchangeable with other FLUKO inline models?
Yes—the 40DG head is mechanically compatible with FLUKO’s F20Z, F30Z, and F40Z platform housings, allowing cross-platform method consistency when scaling shear intensity and flow rate.
What maintenance intervals are recommended for the mechanical seal?
Under continuous operation at ≤80 °C and <1000 cP, inspect the SiC/FKM seal every 500 hours; replace after 2000 hours or upon observed leakage, increased vibration, or audible bearing noise.
Does the unit support variable flow rate control?
No—flow rate is governed by upstream pumping systems. The F40Z-591-S functions as a shear-intensifying module and requires external positive displacement or centrifugal pumps to regulate throughput.
Can it handle abrasive slurries containing >10% solids by weight?
Not recommended—abrasive particulates accelerate wear on the SiC seal faces and rotor-stator edges. For such applications, consult FLUKO’s hardened tungsten-carbide-lined variants (e.g., F40Z-WC series).
