CM-5

Summary

Product identification

• Product Line: Grundfos CM 5 and CME 5
• Type: Horizontal, multistage centrifugal pumps
• Frequency: 50/60 Hz

Operating limits

Performance curves for head (H), pressure (p), power (P₂), efficiency (Eta), and Net Positive Suction Head (NPSH) versus flow rate (Q) are available for:

• CM 5 at 50 Hz
• CM 5 at 60 Hz
• CME 5 at 50/60 Hz

For CME pumps, the 100 % speed is approximately 3400 min⁻¹, irrespective of the input frequency.

See the official PDF for exact tabulated values and performance curves.
