MR Agitators

Product catalog summary
Overview: The Chemineer™ MR Agitators are designed for high performance and value, emphasizing reliability and versatility. They feature a unique gearbox design tailored for agitator use, ensuring long service life and efficient operation.
Gearbox Design: The gearbox is a parallel shaft, helical gear design with a minimum 30,000-hour L-10 bearing life. It includes an oversized output shaft to enhance performance, reducing the need for larger units. This design minimizes gear deflections and vibrations, lowering maintenance costs and extending component life.
Modular Design: The agitators are modular and comply with various standards such as AGMA, OSHA, ANSI, IEC, DIN, EU, and ATEX. They can be fitted with different motors and seals, suitable for both open and closed tank operations. The Chemineer Expert Design System (CEDS) ensures optimal component selection and configuration.
Global Availability: MR agitators are available worldwide and can be interchanged with Chemineer Model 20 HT and GT agitators, facilitating easy adaptation to changing requirements.
Impeller Technology: Chemineer impellers cater to a range of applications, from high flow, low shear liquid-liquid agitation to high shear blending and viscous mixing, ensuring consistent results from lab to full-scale operations.
Features and Benefits: Key features include oversized low-speed shafting, double and triple reduction gearing, bath lubrication, and robust bearing design, contributing to smooth operation, long service life, and reduced maintenance costs.
Seals and Maintenance: The agitators offer various seal options, including cartridge and mechanical seals, designed for easy maintenance and reduced downtime. Optional features like seal shut-off devices enhance safety and operational efficiency.
Dimensions and Configurations: Detailed dimensions for various MR models are provided, highlighting the adaptability of the agitators to different operational needs and configurations.
Contact Information: Contact details for manufacturing and sales facilities in the US, UK, and China are provided.
