CM-PS
The CM-PS is a compact booster solution
designed for domestic and light industrial use.
The booster unit consists of a robust CM pump,
5-way valve and a pressure switch. To complete
the booster system a pressure tank must be
fitted. The pressure switch and pressure tank
ensure a convenient water supply with
a minimum start/stop frequency.
Features
Applications
Robust design
- Mains boosting
- Boosting from above ground water tanks
All wetted parts are made from high quality stainless steel
including the impeller, pump housing and shaft to ensure
the longest life possible.
Automatic operation
The built-in pressure switch automatically starts and stops
the pump according to demand.
Easy installation
The booster unit is a compact solution, which makes
it suitable for most installations. Simply connect your
own pressure tank, inlet and outlet, and you have a fully
operational booster unit.
Great system comfort
The diaphragm tank increases system comfort by limiting
the switching frequency of the pump and compensating for
pressure drops when a tap is opened. It also reduces problems
with water hammer in the pipework.
Motor protection
The single-phase CM pump is effectively protected against
any accidental overload, by built-in thermal and current
protection. This means that no additional motor protection
is required.
