Top Entry Mixers - GTB

Product Description

The MixPro® GTB line of top entry gear drive agitators provides a robust, reliable agitation source for high production industrial environments. The durable, non-proprietary reducer utilizes right angle helical gearing and was designed specifically for abusive applications. The popular GTB design utilizes process matched wet ends for optimum agitation solutions. The ruggedness of the unit has proven itself in abusive applications, consequently minimizing downtime.

Features & Benefits

  • The agitator drive is comprised of a robust non-proprietary reducer which utilizes right angle helical / spiral bevel gear sets. The minimum mechanical service factor of the gear strength as calculated on continuous operation is 1.5, (based on AGMA 6010 standards). The thermal rating of the reducer exceeds its mechanical rating. Larger service factors are available on request.
  • The low speed shaft features a "no-leak" drywell design that physically separates the oil sump from the output shaft to eliminate gear oil contamination of the tank product.
  • Upper reducer seals are grease purgeable to prevent contaminants from destroying the seals and entering the unit.
  • The fabricated carbon steel reducer housing is designed to withstand the stresses of mixing while maintaining accurate gear alignment.
  • Helical and spiral-bevel gear sets are hardened to 58-62 RC and precision ground to a minimum AGMA class ID quality, (based on AGMA 390.03 standards). This provides for quiet operation and higher reducer efficiency. Higher quality gear finishes are available on request.
  • The large diameter, high capacity output shafts are designed to accommodate the high bending moment loads associated with mixing applications. The reducer is sized to accommodate these dynamic loads and provide a minimum bearing L-10 life of 100,000 hours.
  • The agitator drive head is available in a variety of configurations, matched to the specific application (ie. flange mount, plate mount, with tank seal, without tank seal, etc.).
  • Optional tank seal is intricate to the reducer housing, eliminating shaft misalignment.
  • OSHA guarding is standard for increased safety.
  • Readily accessible lubrication and inspection points are incorporated into the design for increased maintenance serviceability.
