Top Entry Mixers - GTH

Product Description

The MixPro® GTH line of top entry gear drive agitators provides a robust, reliable agitation source for high production industrial environments. The durable non-proprietary reducer utilizes parallel helical gearing designed specifically for mixer applications. Our popular GTH 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

  • Agitator drive is comprised of a robust non-proprietary reducer which utilizes parallel helical gearing and has a minimum mechanical service factor of 1.5. The thermal rating of the reducer exceeds its mechanical rating. Larger service factors are available upon request.
  • The low speed shaft drywell feature provides a positive leak prevention of the unit oil sump to eliminate product contamination.
  • Upper reducer seals are grease-purgeable to prevent contaminants from destroying seals and entering the unit.
  • The reducer housing design allows oil from all bearing cavities to be drained through the sump during routine maintenance.
  • Tapered bushing feature provides for easy installation and removal of the mixer shaft while still ensuring a tight connection.
  • 3-bearing low speed shaft design provides greater stability and load-carrying capacities which are typical requirements in mixer applications.
  • Self aligning double row spherical roller bearing allows a higher degree of angular deflection of the drive shaft.
  • Wide, low-speed shaft bearing span allows for greater radial load capacity (ie. greater bending moment capacity). Also, the reducer is sized to accommodate these dynamic loads and provide a minimum bearing L-10 life of 100,000 hours.
  • Agitator drive head is available in a variety of configurations, matched to the application (ie. flange mount, plate mount, with tank seal, without tank seal, etc.).
  • Optional tank seal in the reducer housing eliminates shaft misalignment during installation.
  • OSHA guarding for increased safety.
  • Readily accessible lubrication and inspection points are incorporated into the design for increased maintenance serviceability.
