Flowserve Durco Mark 3 Self-Priming ANSI Pump 2K2x1-10A/93 RV CD4M

The Flowserve Durco Mark 3 Self-Priming ANSI Pump, model 2K2x1-10A/93 RV in CD4M duplex stainless steel, is a robust chemical process pump designed for reliable performance in demanding industrial applications. This self-priming centrifugal pump excels in handling corrosive fluids, slurries, and viscous media, making it ideal for chemical processing, wastewater treatment, and petrochemical industries. Key features include a reverse vane impeller for efficient priming and reduced NPSHr, a seal chamber that accommodates various mechanical seals, and ANSI B73.1 compliance for easy interchangeability. Advantages over similar products include superior corrosion resistance from CD4M material, which outperforms standard stainless steels in aggressive environments, and a design that minimizes maintenance with features like external impeller adjustment and a large seal chamber for better heat dissipation. However, it may require more initial setup for priming compared to non-self-priming models, and its higher cost reflects the premium materials. This unit, manufactured in 1996, shows signs of use but remains functional for refurbishment or spare parts. Overall, it offers high efficiency, with flow rates up to 200 GPM and heads to 250 feet, providing long-term reliability and reduced downtime in critical operations.
