About this product

The all new Durco Mark 3 Group 4 pump offers increased capacity with proven Durco performance and reliability along with ASME B73.1 design features. Offering flow rates to 3861 m3/h (17 000 US gpm) — well beyond ASME size limits — the Durco Mark 3 Group 4 is ideal for high-flow, high-head applications in the chemical processing and general industries.

 

 

Features and Benefits

  • Reverse vane impeller is the only impeller design that offers repeatable pump performance throughout the life of the pump. Open impellers available.

  • Durco SealSentry seal chambers feature flow modifiers that extend seal life by providing optimal seal chamber environments.

  • -Standard sealed bearing housing with labyrinth bearing isolators to keep lubricant in and contaminants out.

  • Two-piece power end design with self-contained bearing housing reduces maintenance costs and facilitates predictive maintenance.

  • Heavy-duty radial and thrust bearings are selected for long life and reliability.

  • External micrometer impeller adjustment accurately sets impeller clearance in 20 seconds, simplifying maintenance.

  • Rugged shaft and bearing design extends seal life, bearing life and reduces shaft deflection and vibration.

 

Specifications

  • Single stage, overhung, centrifugal pump designed to ASME B73.1 Standards. Hydraulic performance, NPSH and vibration testing per Hydraulic Institute (HI) standards.  CE/ATEX Conformance.
