Mark 3 In-Line Overhung Chemical Process Pump

Description: The Durco Mark 3 In-Line pump exceeds ANSI B73.2M design criteria. This space-saving design utilizes the industry-leading Mark 3A power end and other Mark 3 advanced features for maximum Mean Time Between Planned Maintenance (MTBPM).

Mark 3 Sealmatic ANSI Standard, Overhung Pump

Description: The Flowserve Mark 3 Sealmatic pump uses a dynamically sealing repeller to eliminate the need for mechanical seals in tough to seal services. This pump conforms to ANSI B73.1M standards and is completely interchangeable with the industry leading Mark 3A power end.

Mark 3 Lo-Flo Overhung Chemical Process Pump

Description: The Durco Mark 3 Lo-Flo pump is designed to improve pump reliability and performance in low-flow, high-head applications. Its innovative radial vane impeller and circular, concentric casing was developed to reduce radial loads and shaft vibration while extending bearing and mechanical seal life.

Mark 3 ASME (ANSI) Standard Overhung Chemical Process Pump

Description: The Durco Mark 3 pump is recognized as the worldwide leader in ANSI chemical process pumps. This ASME (ANSI) B73.1 design offers the industry's most advanced design features for maximum Mean Time Between Planned Maintenance (MTBPM).

Mark 3 Recessed Impeller, Overhung Chemical Process Pump

Description: The Durco Mark 3 Recessed Impeller pump combines the best design features of the Mark 3 ANSI Standard pump with the vortex action of a recessed impeller.

CPXP Self-Priming ISO Chemical Process Pump

Description: Operating on the reflux priming principle, the CPXP self-priming pump offers state-of-the-art hydraulics, versatile operation and reliable performance while costing considerably less to buy, install and maintain than submersible pumps.
