Product Introduction; Intended Use; Pumped Liquids; Identification - Grundfos CMBE Serie Notice D'installation Et De Fonctionnement

3. Product introduction

These installation and operating instructions are a
supplement to the installation and operating
instructions for the corresponding standard CM
(E) pumps.
For instructions not mentioned specifically in this
manual, see the installation and operating
instructions for the standard pump.
Grundfos CMBE is designed on the CME
platform. CMBE operates at 4000 rpm producing
a unique performance curve from the standard
CME.
CMBE comes complete with a 5-way tee,
pressure tank, pressure sensor, pressure gauge,
and non-return valve. CMBE has built-in dry run
protection.
The pumps have a built-in PI controller and are
set up with a pressure sensor enabling the control
of the pump outlet pressure.
The pumps have been factory-set to constant-
pressure control mode. The pumps are typically
used to keep constant pressure in variable-
demand systems.

3.1 Intended use

The CMBE pump is designed for domestic and
commercial constant pressure applications.

3.2 Pumped liquids

The CMBE pump is designed for pumping water
and other thin, non-aggressive and non-explosive
liquids, which do not contain solid particles or
fibers. If the pump has been used for dirty liquids,
for example, pool water, it must be flushed
through with clean water immediately after use.
