The compact Grundfos CME Booster is suitable for
water supply in domestic applications. The integrated
speed controller keeps a constant pressure in the pipe
system. The pressure sensor constantly monitors
changes in the discharge pressure of the pump and
changes the speed of the pump accordingly.
The optional inlet pressure switch prevents the pump
from operating in case of low inlet pressure.
The booster is very easy to install. When the booster
has been connected to the pipework, it is all a matter
of plugging the plug into a socket, and the system is
operational.
The CME Booster consists of these components:
• CME pump with integrated frequency converter
• 5-way fitting with non-return valve
• diaphragm tank
• pressure gauge
• pressure sensor
• inlet pressure switch (optional).

CME Booster pumps require no external motor
protection. The MGE motor incorporates thermal
protection against slow overloading and blocking
(IEC 34.11: TP 211).
