FEATURES & BENEFITS
The Grundfos CM PS Booster is an automatic booster system for water supply in domestic and agricultural applications as well as other installations where minor leakages are expected to occur. The booster system consists of a Grundfos CM pump, a five-way valve, and a pressure switch. A pressure tank must be fitted to complete the booster system. Grundfos GT tanks make a perfect fit for your booster system. The pressure band is approximately 1 bar. When the system has been connected to the pipes, it is all a matter of inserting the plug into a power supply socket, and the system is operational.
The Grundfos CM PS Booster is mainly used for agricultural and light commercial water supply and similar water installations where minor leakages can be expected.
