Every industrial mixing system is tailored to tank size, slurry density, viscosity and process requirements for optimal performance.

✔ Suitable for All Industries

Agitator mixer systems are widely used across:

  • Upstream Crude & Sludge Storage – Preventing solids deposition, maintaining homogeneity in crude oil storage tanks, and managing heavy BS&W (Basic Sediment and Water).

  • Refinery & Petrochemical Processing – High-intensity blending in reaction tanks, chemical dissolving, emulsification, and gasoline/distillate blending.

  • Drilling Mud & Slurry Fluids – Maintaining uniform density and suspending heavy weighting agents in active mud tanks and reserve pits.

  • Produced Water & Wastewater Treatment – Flocculation, oil-water separation setups, flash mixing, and chemical dosing in industrial environmental circuits.

 

Impeller Options for Industrial Mixers

Axial-Flow Propellers

Ideal for low-viscosity liquids, solid suspension and heat transfer in process tanks.

Radial-Flow Turbine Impellers

Suitable for high-shear applications such as emulsification, gas dispersion and particle breakup.

Anchor & Helical Ribbon Impellers

Designed for high-viscosity products, pastes and gels—perfect for cosmetics, adhesives and thick slurries.

High-Shear / Cowles Impellers

Used for breaking down agglomerates, pigments and producing fine emulsions.

 

Applications of Australian Tank Agitators & Slurry Mixers

Our industrial agitators cover a broad range of mixing duties:

  • Chemical blending and dissolving
  • Water treatment mixing for coagulation/flocculation

  • Crude oil blending and basic sediment suspension

  • Pharmaceutical emulsions and suspensions

 

Petrochemical Compliance & Safety Features

  • Explosion-Proof Motors: Fully ATEX/IECEx compliant drive assemblies engineered for hazardous zone classifications.
  • High-Pressure Mechanical Seals: Advanced sealing technology designed to rigorously prevent hazardous gas leaks and vapor emissions.
  • Corrosion-Resistant Builds: Heavy-duty stainless steel and specialized alloy configurations tailored specifically for petrochemical tanks.

MID-DUTY AGITATOR SK400

The SK400 series dynamic mixing agitator is engineered to handle complex fluid dynamics under harsh processing conditions. Available in both top-entry and side-entry configurations, the SK400 features a high-efficiency motor power range from 0.37kW to 315kW and variable mixing speeds from 1 RPM to 400 RPM. Equipped with an advanced, true dry-well leak-proof structure and a rugged three-point bearing support system, the SK400 eliminates oil contamination risks—making it a highly reliable selection for closed petrochemical tanks and storage vessels.

REACTOR MIXING AGITATOR SK500

The SK500 series reactor agitators deliver high-performance fluid blending engineered for extended operational lifecycles, drastically reducing plant maintenance and downtime. These heavy-duty mixers are purpose-built for sealed pressure vessels, high-pressure reactors, and hazardous chemical processing environments where strict emissions controls and absolute sealing reliability are paramount.

BOTTOM ENTRY AGITATOR SK600

The SK600 series bottom-entry agitators are engineered to provide reliable service and absorb massive mechanical loads in the largest, most demanding industrial operations. It is highly optimized for high-strength processing environments requiring intensive fluid turnover, such as high-viscosity petrochemical blending, heavy sludge waste treatment, and high-velocity gas dispersal applications where top-space on the pressure vessel is limited

Frequently Asked Questions

The primary function of an oil and gas mud agitator is to maintain uniform fluid density and suspend heavy weighting agents (such as barite) within active mud tanks and reserve pits. Continuous mechanical agitation prevents solids from settling at the bottom of the tank, ensuring the drilling fluid retains its required rheological properties for wellbore stability and efficient cuttings transport. For reliable upstream operations, heavy-duty slurry mixers ensure consistent fluid homogeneity before the mud reaches downstream solid control systems.

Selecting the correct tank agitator configuration depends on the tank geometry, fluid viscosity, and specific mixing duties:

  • Side-Entry Agitators: Most energy-efficient for large crude oil storage tanks to prevent the accumulation of BS&W (Basic Sediment and Water) by sweeping the tank floor.
  • Top-Entry Agitators (e.g., Noggrann SK400): Ideal for reaction tanks, chemical dissolving, and medium-to-high viscosity applications requiring multi-level impeller configurations.
  • Bottom-Entry Agitators (e.g., Noggrann SK600): Best optimized for massive industrial vessels requiring intensive fluid turnover, high-velocity gas dispersal, or where headspace on top of the pressure vessel is highly restricted.

Industrial mixers utilized in oil refineries and petrochemical processing must feature robust engineering to operate safely in volatile atmospheres. Crucial compliance and safety features include:

  • Explosion-Proof Motors: Drive assemblies fully compliant with ATEX or IECEx hazardous zone classifications.
  • High-Pressure Mechanical Seals: Advanced sealing technology engineered to strictly prevent fugitive vapor emissions and hazardous gas leaks from closed or sealed pressure vessels.
  • Corrosion-Resistant Builds: Heavy-duty stainless steel and specialized alloys tailored specifically to withstand abrasive mineral slurries and corrosive chemical tanks.

Answer: The selection of the impeller directly determines whether a system delivers low-shear flow or high-intensity dispersion:

  • Axial-Flow Propellers & Hydrofoils: Best for low-viscosity liquids, solid suspension, and gentle blending in crude oil or water treatment circuits.
  • Radial-Flow Turbine Impellers: Engineered for high-shear applications, including gas dispersion, particle breakup, and emulsification in reaction tanks.
  • High-Shear / Cowles Impellers: Specifically utilized for breaking down stubborn chemical agglomerates and producing ultra-fine petrochemical emulsions.

Answer: In critical environments like high-pressure reactors and sealed chemical tanks, mechanical failures are prevented by integrating advanced load-bearing structures. For instance, the Noggrann SK400 and SK500 series mixers use a true dry-well leak-proof structure paired with a rugged three-point bearing support system. This design isolates the drive gear oil from the process fluid, entirely eliminating oil contamination risks while absorbing the massive mechanical loads caused by turbulent fluid dynamics.
