The Biggest, Heaviest Duty Standard Drives Made Specifically for Mixing

The 700/800 series has the capacity to drive long overhung mixer shafts without steady bearings. It has the stamina to withstand severe bending and high-torque loads imposed by fluid forces in the tank. Shafts for 700/800 mixers are larger and stronger. The bearings are sized far in excess of AGMA requirements. Extensive research is conducted to document the limits of shaft and impeller performance under all service conditions.

As a result, you get longer service life with less maintenance. You get our performance guarantee.

You get a mixer with an enviable track record, written by the thousands of 700/800 mixers produced in our state-of the-art plant. You’ll find our 700/800 mixers atop huge fermentation tanks in pharmaceutical production and in all manners of large scale chemical processing. You’ll also find them in the dust and rock of minerals processing,as well as in the heavy sludge of waste treatment.
