Description

This split-coupled end-suction pump has a NEMA standard motor 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 the removal of the motor, motor stool, cover, and impeller without disturbing the pump housing or pipework. It adheres to ISO 5199 standards with adjustments for American dimensions on the pump and its 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. This pump can use an MLE motor with an integrated frequency converter or connect to an external frequency converter for commercial heating applications.
