Open Impeller ASME (ANSI) B73.1 Pump for continuous use in Chemical Process Services

Horizontal Split Case

2

This rugged process pump is ASME (ANSI) B73.1 compliant and operates even in the toughest industrial applications. ANSI 150#, 300#, FF and RF Flanges are available depending on material selection and pump operating pressure. With 31 hydraulics this open impeller design covers a wide range of service conditions (including low-flow region) while providing industry-leading low NPSHR performance and high efficiencies. CPO is designed around a modular concept which allows provision of multiple hydraulics with a small number of power frames. In addition these power frames are interchangeable with models of other common pump manufacturers.

CPO Pump

Telescopic design means that the same coupling guard size can be used for multiple pump and motor combinations. Designed to mount directly to the pump and motor and

therefore does not need to be mounted to the baseplate.
