Chemineer rotating mixers include gear driven top, bottom, and side entering configurations for all your agitation applications. A wide selection of impellers and auxiliary equipment such as seals and lubrication systems are specifically designed to optimize the mixing solution. Also available is a range of small mixers in both direct drive and gear reduced units for standard smaller scale applications.



  • RL-3 RL-3
    The Chemineer RL-3 impeller is designed for applications where a ragless agitator is desired to prevent fibrous material build-up on the rotating impeller. Typical in Waste Treatment applications the RL-3 is a rag shedding impeller which prevents build-up of fibrous materials on the impeller, while providing a strong axial flow for efficient blending and solids suspension.

  • XE-3 XE-3
    The highest efficiency turbulent flow impeller available in the marketplace. Ideal for blending, heat transfer, and solids suspension applications. Developed to maximize strength at lower weights as compared to other axial flow impellers, allowing for longer shafts without internal support, smaller shaft diameters, and smaller seal sizes if applicable.
  • HE-3 HE-3
    An extremely efficient turbulent flow impeller for blending, heat transfer and solids suspension. Most effective for Reynolds numbers over 50. Developed to minimize the creation of trailing vortices and incorporating the otherwise wasted energy into macro-flow.
  • SC-3 SC-3
    The Chemineer® SC-3 Impeller features an advanced design engineered for deep tanks. It produces flow characteristics of much larger impellers, without the added weight, or the resulting loss in pumping efficiency. The highly efficient SC-3 Impeller's reduced weight allows for the use of longer shaft extensions for deeper tanks, and resolves associated critical speed limitations. The use of an SC-3 impeller can produce an overall agitator cost savings as much as 33%.
  • P-4 P-4
    A reasonably cost effective impeller in both turbulent and laminar flow. Good impeller for applications where the viscosity changes over a wide range causing the flow regime to vary between turbulent and laminar flow. A reasonably cost effective impeller for solids suspension.
  • S-4 S-4
    A cost effective impeller for operation very near the floor of a tank for agitating the heel in solids suspension applications. Also an effective impeller in laminar flow applications, especially when impeller Reynolds numbers drop below 50.
  • BT-6 BT-6
    Highest gas dispersing capability available. Can disperse nearly six times the gas handling capability of the D-6 or Rushton impeller. Unloads less than the CD-6. In fact, the unloading is nearly all due to the change in effective density of the gassed liquid. The mass transfer capability is on the order of 10% better than the CD-6. Unlike many other gas dispersing impellers, the BT-6 is relatively insensitive to viscosity.
  • CD-6 CD-6
    The CD-6 impeller is a second generation gas and immiscible liquid dispersion impeller. The CD-6 can handle about 2.4 times the maximum gas capacity of the D-6 impeller. The CD-6 is similar to the Smith impeller, but there are substantial power and dispersion capability differences. This impeller has been used at aeration numbers as high as 2.1.
  • D-6 or Rushton Impeller D-6 or Rushton Impeller
    Good cost effective impeller for low concentrations of immiscible liquid or gas. Two very strong trailing vortices are shed from each blade. These areas of high shear are responsible for breaking the larger droplets to smaller droplets. Maximum aeration numbers should be limited to 0.1.
  • Maxflo W Impeller Maxflo W Impeller
    The Maxflo W impeller, with about 10% more effectiveness in pumping efficiency, is an improved version and full replacement impeller for the Maxflo T. Excellent in abrasive solids suspension, solids suspension in the presence of small amounts of gas introduced or generated in situ, and in boiling or near boiling applications.
  • Maxflo WSE Maxflo WSE
    A high efficiency, advanced side-entering hydrofoil impeller that produces maximum pumping action. It has more cavitation resistance than other designs through effective hydrodynamic design.
  • Maxflow Mark II & III Impellers Maxflow Mark II & III Impellers
    High efficiency, high solidity impellers for use in turbulent side entering applications. They are especially effective for fluids possessing a yield value, such as paper stock. The high solidity permits operation nearer the boiling point without cavitation.
  • JP-3 JP-3
    A high efficiency turbulent flow impeller used on our smallest turbine agitators at direct drive motor speeds on our DT, BTNS and RBTNS agitator lines. The high solidity permits operation nearer the boiling point without cavitation.
  • Smoothline Smoothline
    Chemineer simplifies double impeller configurations for sanitary mixing processes with its patent-pending Smoothline impeller design. It is available for the HE-3, P-4, S-4 and Maxflo W impellers. Smoothline-style impellers disassemble to pass through manways on process vessels. Their FDA-approved Teflon gaskets between every joint prevent entrapment of process material. As an added benefit, they are easily compatible with single piece shafts thus ensuring optimum straightness, efficient energy transmission and superior mixing performance.
  • ChemShear ChemShear
    ChemShear Impellers are made in 4 different styles. Style 1 has the widest blades and style 4 the narrowest blades. Various processes require different ratios of shear and pumping. The wider blades pump more, and the narrower blades have the higher level of shear. They work well in applications which require moderately high shear but also some level of pumping. Many high shear devices are very low in pumping capability and require an auxiliary impeller to provide turnover. ChemShear impellers often overcome the need for an auxiliary pumping impeller. ChemShear impellers have been used in microencapsulation processes producing particles in the 2 micron range.
  • Double Helical Ribbon Impeller Double Helical Ribbon Impeller
    Generally recognized as the best all around high viscosity, laminar flow impeller. It is the most efficient blender of all existing close clearance agitators. The double flight helical ribbon impeller is also good for heat transfer and blending of liquids and solids from the surface. Generally used for applications where viscosities are ordinarily greater than 30,000 MPa.
  • Single Flight Helical Ribbon with Screw Single Flight Helical Ribbon with Screw
    A reasonably efficient high viscosity, laminar flow impeller. Blend times are about the same to somewhat longer than the double flight helical ribbon impeller. The central screw can effectively pull down solids and liquids from the surface when the helical ribbon is pumping up. Generally used for applications where viscosities are ordinarily greater than 30,000 MPa. Heat transfer coefficients are only slightly less than the double helical ribbon impeller.
  • Anchor Impeller Anchor Impeller
    The anchor impeller is the most economical laminar flow impeller. It is most effective in squatty batches where vertical pumping is not as important as in tall batches. Blend times are somewhat longer than helical ribbon type impellers. It is the easiest high viscosity impeller onto which scrapers can be mounted for very difficult heat transfer applications.
  • Screw (Auger) Impeller Screw (Auger) Impeller
    A screw impeller produces effective high viscosity blending of shear sensitive polymers. This impeller provides good top-to-bottom turnover. Although blending is generally good, heat transfer is not as good as the close clearance high viscosity impellers. The screw impeller is suitable for fluids which are not too pseudoplastic with power law indexes less than 0.5.
