Ruhrpumpen - Model CPO ANSI -Process Pump

With +30 hydraulics, the CPO pump line is designed to meet and exceed theANSI/ASME B73.1 specification. Its open impeller design covers a wide range of service conditions (including a low flow region with our CPO-L model) while providing industry-leading low NPSHR performance and high efficiencies.

The CPO pump is designed around a modular concept which allows the provision of multiple hydraulics with a small number of Power Frames. In addition, these Power Frames are completely interchangeable with models of other common ANSI pump manufacturers.

• Horizontal, overhung, single stage, end suction ANSI process pump
• Foot mounted, back pull-out design for ease of maintenance
• Dimensional interchangeability with most common ANSI/ASME B73.1 pump manufacturers
• Open impeller design allows handling of solids in suspension. The impellers are locked onto the shaft by threads and sealed with an O-ring
• External impeller adjustment sets impeller quickly and accurately without the need for special tools
• Machined flat surface suitable for use with magnetic mount vibration probe
• Double row, angular contact thrust bearings minimize axial shaft end-play thus maximizing mechanical seal life
• A robust solid shaft with outstanding L3/ D4 for low vibration and increased mechanical seal life(shaft sleeves are available as an option)
• INPRO VB45-S^TM labyrinth bearing isolators to avoid bearing contamination
• Lubrication:
  • Oil bath lubrication as standard, with option for grease and oil mist lubrication
  • Large capacity oil sump and finned housing provide superior cooling
  • Optional finned oil cooler

• C-Frame motor adapter
• Different baseplate mounting systems
• Sealing
  • Large taper bore with flow modifiers
  • Standard large and small bore
• Cooling coil to maintain proper oil temperature in hot applications
