GMX Series - Large Tank Mixers & Industrial Agitators

Designed for high efficiency in large tanks, the GMX Series handles medium to heavy-duty applications. Large tanks (2,500 – 30,000 + Gallons) require the design integrity and control offered by our drive and shaft designs. This large tank mixer is available with design guarantees, and prompt supply.

Precision gearboxes are critical to the operation and reliability of our mixer designs. Our drives are built on a one-piece case to ensure rigid and precise torque and shaft performance. Cases are machined in a single operation ensuring the long life and low maintenance of the sealing and bearings. Available in both helical and bevel helical gear configurations, our team can select and configure a mixer to suit your needs.

Oversized tapered roller bearings to manage overhung loads as calculated for your application and tank height. Increased capacity in either overhung (radial) or thrust (axial) loading ensures that premature bearing failure will not occur due to high stresses in the bearing elements. The increased bearing capacity optimizes the gearbox for mixing applications.

  • Spread bearings optimize shaft designs
  • Oil-safe seal system
  • Auto breather regulates internal pressure and keeps contaminants out
  • Solid gear case housing to minimize torsion
  • Mount designs to suit your tank: flange, plate, other
  • Case-hardened, high-quality gearing (Rockwell 60 C typical / up to AGMA Class 13)
  • Standard sealing technologies to suit your operation and budget; double or quadruple lip seals, packing, and mechanical seals to suit your application or brand requirement
  • Stainless steel (316) protective paint coating – USDA/H1 compliant in protective features and options for severe duty and wash-down environments


Full line of impeller options: pitch, radial, P3B radial flow, and our unique Dynaflow high-efficiency impeller.
