Product features
Overview
The Ruhrpumpen CPO is a single-stage, horizontal ANSI/ASME B73.1 process pump (overhung, end-suction) with an open impeller. Designed for heavy-duty (petro)chemical and industrial applications, it offers low NPSHr and high efficiency. The CPO handles up to approx. 1,590 m³/h and heads up to 198 m, with pressures up to around 26 bar and temperatures up to 371 °C. Its back-pull-out design and modular power frame allow for easy maintenance and part interchangeability.
Additional Information
The CPO line includes over 30 hydraulics and is dimensionally interchangeable with many common ANSI brands. The externally adjustable open impeller handles solids in suspension and maintains performance, while double-row angular contact thrust bearings minimize axial play and extend mechanical seal life. INPRO VB45-S™ labyrinth bearing isolators protect against contamination; lubrication options include oil bath (standard), grease, or oil mist. Available options include a C-frame motor adapter, various baseplates, large/small/taper bore seal chambers, and oil cooler/coil for hot service applications. For low-flow, high-head duties, the CPO-L version features a radial vane impeller and concentric casing.
