Flowserve Mark 3 ISO Pump

The Flowserve Mark 3 ISO pump is a chemical process pump which provides outstanding hydraulic performance, unrivalled reliability and low total cost of ownership. Conforming to ISO 2858 and ISO 5199 design criteria, the Mark 3 ISO incorporates many proven reliability- and performance-enhancing features.

The main benefits are:

  • Renewable, high-efficiency performance over the life of the pump with the reverse vane impeller
  • Optimal, predictable seal chamber pressures that are re-established after every impeller setting
  • Maximal mechanical seal life due to an ideal seal environment created by the SealSentry seal chamber
  • Two-piece bearing bracket reduces inventory cost and facilitates retrofit for ISO 2858 compliant pumps
  • Robust shaft and bearing designs that minimize shaft deflection and extend mechanical seal and bearing life
  • Fast and accurate impeller setting with the industry’s most innovative external impeller adjustment mechanism
  • In-shop reverse vane impeller adjustment with the only pump that takes full advantage of the back pull-out design Global Design, Unmatched Performance

The Flowserve Mark 3 ISO pump is a centrifugal pump which is available in many designs to meet the needs of the process industries:

What is the main difference between the Durco Mark 3 Pump and the Flowserve Mark 3 ISO pump?

The Durco Mark 3 Pump is an ANSI / ASME pump and is an American design whereas the Flowserve Mark 3 Pump is an ISO pump and is a Spanish/European design. The Flowserve Mark 3 ISO pump also has more hydraulic sizes to choose from and the flange ratings are an added benefit.
