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.
