Mark 3 ASME (ANSI) Standard Overhung Chemical Process PumpMark 3 ASME (ANSI) Standard Overhung Chemical Process Pump

Brand: Durco
Description:

The Durco Mark 3 pump is recognized as the worldwide leader in ANSI chemical process pumps. This ASME (ANSI) B73.1 design sets the global benchmark for reliability, hydraulic performance, and mechanical seal life in chemical processing environments. With its overhung, end-suction design, the Mark 3 is ideal for transferring corrosive, toxic or high-temperature fluids in demanding industrial systems.

Engineered by Flowserve, the Mark 3 pump provides modular construction, robust shaft support and advanced sealing options, making it the preferred choice for applications in chemical manufacturing, refining, pulp and paper and general industry. Its design helps lower maintenance costs, extend mean time between repairs (MTBR) and ensure process uptime even in harsh conditions.
