CB Series Horizontal Centrifugal pumps

Summary

Product identification

The CB Series are two-stage horizontal centrifugal pumps designed for high hydraulic performance. They feature two opposite impellers with balanced axial thrust for high efficiency.

Applications

• Pressurization systems
• Small irrigation
• Handling of non-aggressive liquids
• Washing systems

Operating limits

• Type of liquid: Clear or slightly turbid non-abrasive water
• Maximum liquid temperature:
  • 40°C for 0.55 - 0.75 kW models
  • 90°C for 1.1 - 4.0 kW models
• Maximum suction height recommended: 5 m with foot valve
• Maximum operating pressure:
  • 6 bar for 0.55 - 0.75 kW models
  • 10 bar for 1.1 - 4.0 kW models

Electrical
