CME-10

Summary

Product identification

The Grundfos CME 10 is a horizontal, multistage centrifugal pump. CME pumps are built upon the CM pump range, distinguished by their Grundfos MGE motor. This motor is designed to EN standards and incorporates a frequency converter, enabling continuously variable control of motor speed.

CME pumps are suitable for applications requiring:

• Controlled operation with fluctuating consumption
• Constant pressure
• Communication with the pump

Benefits of frequency-controlled speed include energy savings, increased comfort, and enhanced control and monitoring of the application and pump performance.

The CME 10 is available in:

• Cast-iron version (CME 10-A)
• Stainless-steel versions (CME 10-I and CME 10-G)

Operating limits

CME pumps operate at 50/60 Hz. The 100% speed of CME pumps is approximately 3400 min⁻¹, irrespective of the input frequency.

Performance curves for Head (H), Flow rate (Q), Input Power (P₂), Net Positive Suction Head (NPSH), and Efficiency (Eta) are available for CME 10 models, showing a range of operation from minimum to maximum performance curves. See the official PDF for exact tabulated values and performance graphs.

Electrical

CME pumps are available with the following supply voltages:

• 1 x 200-240 V, 50/60 Hz (supply voltage K)
• 1 x 208-230 V, 50/60 Hz (supply voltage M)
• 3 x 380-480 V, 50/60 Hz (supply voltage L)
• 3 x 460-480 V, 60 Hz (supply voltage N)

Output power (P₂) for CME 10 models ranges from 1.10 kW to 5.5 kW.

Communication & Control

Communication with CME pumps is possible via:

• Central building management system: Allows remote monitoring and changes to control modes and setpoint settings.
• Remote control (Grundfos R100): An accessory that enables communication by pointing an IR-signal transmitter at the control panel of the terminal box to monitor and change settings.
• Control panel: Allows manual adjustment of setpoint settings on the CME pump terminal box.

Communication Interface Units (CIUs) are available for network integration:

• CIU 100: LON
• CIU 150: PROFIBUS DP
• CIU 200: Modbus RTU
• CIU 250: GSM
• CIU 270: GRM
• CIU 300: BACnet MS/TP

CME pumps can connect to LON, PROFIBUS, Modbus, GSM, GRM, or BACnet networks.

Grundfos WinCAPS and WebCAPS selection programs can calculate specific duty points and energy consumption for CME pumps.
