Discover the Raven 3850 Series Mixer Drive, engineered for longevity and precision in industrial mixing applications. This flagship solution is built to excel under the harshest conditions while optimizing your operations.

Raven 3850 Series Mixer Drive

The Raven 3850 Series Mixer Drive represents the pinnacle of industrial mixing technology. Designed by Philadelphia Mixing Solutions, it offers unmatched durability, precision, and efficiency for applications ranging from chemical processing to wastewater management. Advanced features—including a piloted C-face motor mount and precision-engineered gears—ensure reliable performance even in the most challenging environments.

Key Features

Piloted C-Face Motor Mount Design: Eliminates foot-mounted alignment issues, enhancing stability and longevity.
Precision Bearings: Oversized tapered roller bearings handle high shock and overhung loads, extending gearbox life.
Gear System: Carburized and ground helical gears ensure smooth, quiet operation with superior shock load capacity. Tip and root relief plus crowning prevent edge loading on gear teeth.
Durable Mixer Housing: Closed-grain cast iron with inspection windows and heavy-duty gussets to minimize deflection and increase thermal rating.
Drywell Design: Non-contacting mechanical drywell prevents oil leaks at the output shaft, reducing maintenance and environmental risk.
Input Shaft Sleeve: Hardened, replaceable sleeve extends the life of input shaft oil seals.
Output Shaft: Centered with a lower taper collar assembly to minimize runout. Solid output shaft standard on size 3863M; optional for other sizes.
Guardian Package: Enables accurate oil sampling to reduce wear and repair costs.
Fully Straddled Pinions: Supported on both ends with bearings to minimize shaft deflection and ensure proper gear tooth contact.
Raised Gasket Surfaces: Prevents water ingress by eliminating wicking from pooled rainwater through gasket surfaces.
Lubrication at Theoretical Zero RPM: Dip lubrication design ensures effective lubrication at low speeds, ideal for Variable Frequency Drive applications.
Oil Sump: Funnels foreign particles away from gear and bearing meshes to protect internal components.

Theory of Operation

The Raven 3800 Series Mixer Drive utilizes a robust drive mechanism with precision-engineered gears and bearings to deliver consistent torque for demanding mixing applications. Its piloted motor mount ensures optimal alignment, while the unique drywell design eliminates potential oil leaks. The integrated Guardian Package allows for proactive maintenance by enabling continuous monitoring of lubrication health, ensuring minimal downtime and extended operational life.
