The Chemineer® Model 20 HT/GT top-entering agitators feature a swing out seal change design for easy seal maintenance and reduced maintenance cost. For replacement of the mechanical seal, simply rotate the gearbox 90° around the pivot pin. The top of the seal pedestal opens for a clear, line-of-site view and ample room for easy removal of the coupling half and seal assembly. The product features a new, high-efficiency gearbox with helical gearing and a parallel shaft configuration. The unit features a modular design package that reduces the number of replacement parts needed to be carried in inventory. The product is designed to meet AGMA, OSHA, ANSI, IEC, DIN, EU and ATEX standards and requirements, and a variety of seal options are available for application versatility.
