Impeller Options — Matched to Your Process


Mixing performance starts with impeller selection. The TPMX Series offers a range of sanitary impeller geometries, each engineered for a specific flow pattern, viscosity range, and process outcome — so you get the right hydraulic result for blending, suspension, dispersion, or gentle handling of shear-sensitive products.


Marine Propeller- Delivers strong axial flow for fast, efficient bulk blending and homogenization of low-to-medium viscosity liquids. Ideal for general-purpose mixing, blending of miscible liquids, and maintaining uniform tank turnover with low power consumption.


Hydrofoil Impeller- A high-efficiency, low-shear axial flow impeller designed to maximize bulk fluid motion per unit of power. Well suited for blending, heat transfer applications, and solids suspension where shear-sensitive products — such as pharmaceutical suspensions or dairy formulations — need to be mixed gently without damaging product structure or texture.


Turbine Impeller- Generates strong radial flow and high shear, making it effective for dispersing powders into liquids, gas-liquid dispersion, and applications requiring rapid mass transfer. A preferred choice for emulsification and applications where localized high-intensity mixing is required near the impeller zone.


Cowl Disk Impeller (Draft Tube / Rotor-Stator Type)- Combines pumping and high-shear dispersing action within a cowl or draft tube, driving strong top-to-bottom fluid circulation while breaking down agglomerates, powders, and difficult-to-wet ingredients. Excellent for powder incorporation, dissolving, and de-agglomeration in high-viscosity or hard-to-disperse formulations common in food and pharma processing.


Multi-Stage & Combination Configurations- For complex batches, two or more impeller types can be mounted on a single shaft at different levels — for example, a Cowl Disk near the liquid surface for powder incorporation paired with a Hydrofoil lower in the vessel for bulk blending — delivering complete, uniform mixing in a single pass.


Our engineering team selects and sizes the optimal impeller (or combination) based on your vessel geometry, batch volume, viscosity, and process objective, ensuring TPMX performance matches or exceeds equivalent Inoxpa configurations.


Applications


Food & Beverage- Dairy blending, juice and beverage batching, sauce and dressing manufacturing, syrup preparation, flavor and additive dispersion, yeast propagation.


Pharmaceutical & Nutraceutical- API blending, suspension and emulsion preparation, ointment and cream manufacturing, syrup and oral liquid mixing, buffer and media preparation for bioprocessing.


Personal Care & Cosmetics- Lotion, cream, and gel homogenization requiring high hygiene standards.

TUFFMIX BPMX Series


Sanitary Bottom Entry Agitators for Food & Pharmaceutical Processing


Engineered for hygiene, built for performance — the TUFFMIX® BPMX Series Sanitary Bottom Entry Agitator is the trusted mixing solution for processors who cannot compromise on product quality, contamination control, or process consistency.


Designed specifically for the demanding standards of the food, dairy, beverage, pharmaceutical, and biotechnology industries, the BPMX Series delivers efficient, low-shear to high-shear mixing performance while meeting the strictest sanitary and hygienic design requirements. Every agitator in this range is built to ensure smooth product flow, and full CIP/SIP compatibility — giving you a mixing system that is as clean as it is powerful.


Why Choose the TUFFMIX BPMX Series?


Hygienic by Design- The BPMX Series follows sanitary construction principles with crevice-free wetted surfaces, mirror-polished internal finishes, and smooth continuous welds — eliminating product entrapment zones and minimizing microbial growth risk. This makes it ideally suited for aseptic and hygienic processing environments common in food, dairy, and pharmaceutical applications.


Bottom Entry Advantage - Unlike top or side entry designs, bottom entry mounting allows for a low-profile installation, easier vessel access, reduced headroom requirements, and superior mixing efficiency — especially valuable in low-level and shallow-batch applications where top entry agitators struggle to maintain effective mixing.


Robust Sanitary Sealing- The BPMX Series is available with a range of hygienic mechanical seal configurations — including single, double, and cartridge-type seals — ensuring zero product leakage, contamination prevention, and long, trouble-free operational life even under continuous duty cycles.


CIP/SIP Compatible - Fully compatible with Clean-in-Place and Steam-in-Place protocols, the BPMX Series supports automated cleaning and sterilization cycles, reducing downtime and ensuring consistent hygiene validation for regulated industries.


Materials of Construction- Manufactured using high-grade AISI 316L/316 stainless steel, with contact parts finished to Ra ≤ 0.8 µm (and finer on request) to meet stringent food-grade and pharma-grade surface finish requirements. FDA, 3A, and GMP compliant construction options are available to match your regulatory needs.


Variable Speed & Torque Control- The BPMX Series can be configured with fixed-speed, variable frequency drive (VFD), or gearbox-driven arrangements, giving you precise control over mixing intensity, shear rate, and blend time — tailored to your product's rheology and process sensitivity.
