Raven 3800 Series Mixer Drive




One of our most versatile performers, the Raven 3800 is a next-generation top entry mixer drive with a wide range of potential applications. Whatever the task, it will provide long-term reliability, even in harsh operating conditions. Potential applications include:


Industrial Wastewater

Water & Wastewater

Pulp & Paper

Mineral Processing


The Raven 3800 is suitable for use in most top-entry mixing tasks. Capable of handling some of the most demanding industrial mixing jobs, it’s an ideal choice for solid suspension, gas dispersion and liquid-liquid dispersion, where it will deliver improved heat transfer, mass transfer and blending — critical priorities for maintaining efficiency and quality control in the chemical process industry.

Other applications include water and wastewater treatment — with a high torque/low horsepower design, the Raven 3800 can maximize flow rates while reducing energy usage, whether it’s being used for flash mixing, flocculation, lime softening, surface aeration or related processes.

  • PINIONS AND GEARS: Carburized and ground helical gears provide quiet operation with many years of service life
  • PILOTED C-FACE MOTOR MOUNT DESIGN: Eliminates foot mounted alignment issues that could lead to premature failure
  • SELF-LUBRICATING AT THEORETICAL ZERO RPM: Dip lubrication eliminates the need for external lubrication kits when variable speed drives are used for low impeller speed operation.
  • END COVER: Designed to eliminate leak paths and minimize motor vibrations
  • TAPERED ROLLER BEARINGS THROUGHOUT GEARBOXES: Precision tapered roller bearings handle high shock and large overhung loads
  • MIXER HOUSING: Inspection windows allow convenient internal inspection without removing the motor or end plate.
  • EXTRA GUSSETING: Provides rigidity to handle loads exerted on the housing by the mixing and agitation forces, leading to longer bearing and gear life
  • DRYWELL DESIGNS: Eliminate oil leaks from the output shaft.
  • GUARDIAN PACKAGE OPTION: Provides simple, fast, accurate oil sampling
