Description
This split-coupled end-suction pump has NEMA MLE motors and ANSI flange fittings. It is a non-self-priming, single-stage centrifugal volute pump with an axial inlet port, radial outlet port, and horizontal shaft. The back pull-out design allows for motor, motor stool, cover, and impeller removal without disturbing the housing or pipework. It adheres to ISO 5199 standards with American dimensions on the pump and flanges. Inlet and outlet flanges conform to ASME 16.1/16.42 standards with performance rated at 175/363 PSI (12/25 bar). The mechanical shaft seal follows EN 12756 dimensions, while motors meet NEMA standards and can include an integrated frequency converter or connect to an external one for enhanced control in applications like water treatment fertigation and irrigation systems.
