The MR model is the latest addition to Chemineers line of high performance and reliable agitators. The MR agitators gearbox is a proprietary, parallel-shaft, helical gear design that features minimum 30,000 hour L10 bearing life and an oversized output shaft for optimal performance and extended service life. Shaft speed selections are available from 7 to 380 rpm without the use of auxiliary reducers or electronic drives. When the MR gearbox is expertly matched with a wide variety of Chemineer impellers and other system components, MR agitators are capable of economically meeting your blending, dispersion, and other mixing needs.
GEARBOX DESIGNED FOR AGITATOR DUTY
Commercially available gearboxes for agitators in this size range normally have low-speed output shafts and bearing designs that are poorly suited to agitator duty. Commercial gearboxes typically use smaller diameter output shafts, resulting in the need to select larger and more expensive units to handle the torsional loads and bending moments produced by the hydraulic loads on agitator systems. These smaller output shafts and less robust bearing designs of commercial gearboxes also contribute to higher gear deflections, excessive vibration, higher maintenance costs, and a reduced life of many critical agitator system components. The MR gearbox addresses these concerns by incorporating a larger output shaft straightened to exact tolerances and high capacity tapered roller bearings into its design.
