Flowserve Durco 2K3x1.5-10ARV MK3 STD Chemical Process Centrifugal Pump

The Flowserve Durco Mark 3 (MK3) Standard centrifugal pump is a robust, ANSI-compliant chemical process pump designed for demanding industrial applications in chemical processing, petrochemical, pulp and paper, and general industry sectors. This model, sized 2K3x1.5-10ARV, features a reverse vane impeller for improved efficiency, reduced NPSHr, and extended seal life by minimizing pressure on the seal during operation. Constructed with durable materials like ductile iron or alloy (material code D4), it offers excellent corrosion resistance and reliability in handling aggressive fluids, slurries, and corrosive chemicals. Key advantages include a micrometer-style impeller adjustment for precise clearance settings without disassembly, a SealSentry seal chamber for enhanced sealing options, and compliance with ANSI B73.1 standards for easy interchangeability. Benefits over similar products include lower maintenance costs due to its Power End design with lifetime bearing warranties, higher efficiency (up to 80% in optimal conditions), and versatility in handling temperatures up to 500°F and pressures up to 275 PSI. Drawbacks may include higher initial cost compared to non-ANSI pumps and the need for proper alignment to avoid vibration issues. This used unit from 2012 shows moderate wear but remains suitable for refurbishment, offering cost-effective performance for fluid transfer, circulation, and boosting applications.
