ASME / ANSI B 73.3 standards compliant, non-metallic, magnet drive centrifugal pump with flows to 675gpm (153m³/hr) and Heads to 320ft (97m). Our most flexible and popular sealless magentic drive pump.

The K Plus is an ASME / ANSI B73.3 standard chemical process sealless magnetic drive non-metallic centrifugal end suction pump.

The K Plus is also available in a low process temperature configuration.


This ASME / ANSI standard pump covers a wide range sizes and includes standard external dimensions so that pumps manufactured by other suppliers are dimensionally interchangeable with highly reliable Sundyne ANSIMAG sealless magnetic drive pumps without changing piping or baseplates. Our sealless magnetic drive pumps meet standard design specifications and materials of construction.

- Flows up to 675 GPM (153 m³/hr)
- TDH up to 320 ft. (97m)

The K Plus is also available in a Low System Temperature configuration and is ideal for most corrosive or acidic applications in the Chemical, Specialty Chemical, and Steel industries.
