APD Series Top Entry Mixer from Cleveland

APD, Series, Top Entry, Mixer, ClevelandThe APD series mixer is designed for demanding applications where a broad range of output speeds is needed. Special attention has been given to those applications that require low output speeds in non-Newtonian fluids (shear thinning) coupled with larger impeller diameters; but without sacrificing service factor (based on AGMA Class III Service) or efficiency.

This product series has been developed for tank volumes from 2,000 gallons to over 100,000 gallons. Invested torque ratings are from 180 inch pounds to 51,000 inch pounds, horsepower ranges from 1 to 30.

A new product design from Cleveland Mixer, the APD series has successfully completed a rigorous 2 year field test in an application with aggressive agitation levels, high impeller side loading (to test the strength of the gearbox gearing and bearings) and constant, 24 hour a day, 7 day per week service.

The mixers are available in both open and closed tank configuration. Closed tank applications with lip seals, stuffing boxes or mechanical seals are available.
