Flowserve Durco Mark 3 ISO MAG

Flowserve Durco Mark 3 ISO MAG addresses toxic, explosive, valuable and environmentally sensitive process liquids. It is relevant where equipment selection must balance hydraulic or process duty, operating reliability and maintainability. Correct sizing and configuration are important because unsuitable selection can increase energy use, wear and unplanned downtime.

The series uses ISO chemical-process platform with hermetically sealed magnetic drive and back-pullout construction. This construction is intended to provide stable process performance while giving maintenance teams a practical basis for inspection, servicing and component replacement. Configuration options should be matched to the pumped medium, installation arrangement and required operating point.

Current technical data for the series include flows to 475 m³/h; heads to 150 m; pressures to 25 bar; temperatures from -40°C to 300°C. These limits and options are selection criteria rather than universal operating points, so the final duty should be checked against the exact pump or valve configuration.

For lifecycle cost, the main value comes from selecting the correct hydraulic or control configuration and maintaining the equipment before wear develops into a process interruption. AxFlow can support model selection, service planning and spare-parts requirements to help reduce downtime risk over the equipment life.
