CM-10

Summary

Product Identification

The GRUNDFOS CM 10 is a series of horizontal, multistage centrifugal pumps designed for operation at 50/60 Hz.

Available variants include:

• CM 10-A: Cast iron (EN-GJL-200) construction.
• CM 10-I: Stainless steel (EN 1.4301/AISI 304) construction.
• CM 10-G: Stainless steel (EN 1.4401/AISI 316) construction.

Operating Limits

Detailed performance curves (Q [m³/h], H [m], p [kPa], P2 [kW], NPSH [m], Eta [%]) for CM 10 pumps are available for both 50 Hz and 60 Hz operation. See the official PDF for exact graphical representations.

Electrical

The CM 10 series supports various supply voltages and frequencies:

• 50 Hz:
  • 1 x 220-240 V (supply voltage C)
  • 3 x 220-240 V / 380-415 V (supply voltage F)
  • 3 x 200/346 V (supply voltage G)
• 60 Hz:
  • 1 x 115/230 V (supply voltage B)
  • 1 x 220 V (supply voltage A)
  • 3 x 208-230 V / 440-480 V (supply voltage E)
  • 3 x 575 V (supply voltage H)
  • 3 x 200-220/346-380 V (supply voltage G)
• 50/60 Hz (Dual Frequency):
  • 3 x 400 V (supply voltage I) - Note: Until further notice, pumps for supply voltage I are only suitable for connection to a frequency of 60 Hz. A dual frequency version was expected to be ready for sales in January 2011.
  • 3 x 380-415 V, 50 Hz; 3 x 440-480 V, 60 Hz (supply voltage J)
  • 3 x 220-240/380-415 V, 50 Hz; 3 x 220-255/380-440 V, 60 Hz (supply voltage O)

Motor output power (P2 [kW]) varies by pump type, frame size, and supply voltage/frequency. See the official PDF for exact tabulated values.

Mechanical / Hydraulic
