ANSI / ASME B73.1 process pump

Ruhrpumpen CPO / CPO-L

 

 

Ruhrpumpen CPO Process Pumps: Versatile Performance According to ANSI/ASME B73.1

With over 30 hydraulic options, the CPO pump line is designed to meet and exceed ANSI/ASME B73.1 specifications. The open impeller design offers a wide range of application possibilities (including a low-flow option with the CPO-L model), delivering industry-leading low NPSHr performance and high efficiency.

The CPO pump is based on a modular design concept, allowing for multiple hydraulic configurations with a limited number of power frames. Additionally, these power frames are fully interchangeable with models from other commonly used ANSI pump manufacturers.

FEATURES

  •  Designed for the most demanding applications, equipped with an advanced open impeller, CD4MCu wetted parts as standard, and a robust power frame.

  •  Horizontal, single-stage, end suction ANSI process pump

  •  Foot-mounted, back pull-out design for easy maintenance

  •  Dimensionally interchangeable with most ANSI/ASME B73.1 pump brands

  •  Open impeller design allows handling of suspended solids; impeller is threaded onto the shaft, locked in place, and sealed with an O-ring

  •  External impeller adjustment for quick and precise setting without special tools

  •  Machined flat surface suitable for magnetic vibration probe

  •  Double-row angular contact thrust bearings minimize axial shaft movement for longer mechanical seal life

  •  Sturdy solid shaft with excellent L3/D4 ratio for low vibration and extended seal life (optional shaft sleeves available)

  •  INPRO VB45-STM labyrinth bearing isolators to prevent bearing contamination

OPTIONAL FEATURES

  •  C-frame motor adapter
  •  Various baseplate mounting systems
  •  Seals: large tapered bore with flow modifiers
  •  Cooling coil to maintain optimal oil temperature for hot applications

CPO-L: Specially Designed for Low Flow, High Head Applications
The CPO-L is specifically designed to address the need for low flow within the CPO range. It features a radial impeller developed to reduce thrust and pressure in the seal chamber, a common challenge in low-flow applications. This pump also complies with the ANSI/ASME B73.1 standard.

In low-flow applications, minimizing radial load and potential shaft deflection issues is essential. The radial impeller and concentric pump casing of the Ruhrpumpen CPO-L are specifically engineered to address these challenges in low-flow or throttled operating conditions. The radial impeller with balance holes further reduces pressure in the seal chamber, leading to longer seal and bearing life and improved reliability.
