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.
