Durco Mark 3 Metallic, Sealed, ASME (ANSI) Chemical Process Pump
Brand: Flowserve DurcoConforming to ASME (ANSI) B73.1, Durco Mark 3 pumps incorporate many proven reliability- and performance-enhancing features.
They are available in a wide range of configurations, including mechanically sealed, dynamically sealed, sealless magnetically driven, low-flow, self-priming and recessed impeller.
It provides flexibility and breadth of pumping solutions in countless applications.
Features- Lower total cost of ownership from reverse vane impeller, which eases maintenance and provides renewable, high-efficiency performance over the pumps’ life
- Increased reliability and mechanical seal life due to the ideal seal environment created by the SealSentry seal chamber
- Ease of maintenance resulting from optimal, predictable seal chamber pressures that are re-established after every impeller setting
- Extended mechanical seal and bearing life through robust shaft and bearing designs that also minimize shaft deflection
- 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
