CM-15

Summary

Product Identification

The GRUNDFOS CM 15 series consists of horizontal, multistage centrifugal pumps, available in 50/60 Hz versions.

Available variants include:

• CM 15-A / CME 15-A: Cast iron (EN-GJL-200) construction.
• CM 15-I / CME 15-I: EN 1.4301/AISI 304 stainless steel construction.
• CM 15-G / CME 15-G: EN 1.4401/AISI 316 stainless steel construction.

Performance Data

Performance curves for CM 15 models at both 50 Hz and 60 Hz are provided, illustrating:

• Flow rate (Q) in m³/h and l/s
• Head (H) in m
• Pressure (p) in kPa
• Power input (P2) in kW
• Net Positive Suction Head (NPSH) in m
• Efficiency (Eta) in %

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

Electrical

The CM 15 and CME 15 pumps are available with various supply voltage configurations:

• Single-phase, 50 Hz (supply voltage C): 1 x 220-240 V
• Three-phase, 50 Hz (supply voltage F): 3 x 220-240 V / 380-415 V
• Three-phase, 50/60 Hz (supply voltage G): 3 x 200/346 V, 50 Hz; 3 x 200-220/346-380 V, 60 Hz
• Three-phase, 60 Hz (supply voltage E): 3 x 208-230 V / 440-480 V
• Three-phase, 60 Hz (supply voltage H): 3 x 575 V
• Three-phase, 50/60 Hz (supply voltage I): 3 x 400 V (Note: Pumps for supply voltage I were only suitable for 60 Hz at the time of document publication, with a dual-frequency version expected in January 2011.)
• Three-phase, 50/60 Hz (supply voltage J): 3 x 380-415 V, 50 Hz; 3 x 440-480 V, 60 Hz
• Three-phase, 50/60 Hz (supply voltage L) for CME models: 3 x 380-480 V
• Three-phase, 60 Hz (supply voltage N) for CME models: 3 x 460-480 V
• Three-phase, 50/60 Hz (supply voltage O): 3 x 220-240/380-415 V, 50 Hz; 3 x 220-255/380-440 V, 60 Hz (Note: CM 15-2 and CM 15-3 (A models) and CM 15-1, CM 15-2, CM 15-3 (I/G models) are not available with supply voltage O.)

Mechanical / Hydraulic

Materials of Construction
