Product Description
CMB 3-37 I-C-A-A-P-A
The Grundfos CM Booster PS is an automatic booster system for water supply in domestic and agricultural applications as well as other installations where small leakages are expected to occur. The booster system consists of a Grundfos CM pump, a 5-way valve and a pressure switch. A pressure tank must be fitted to complete the booster system. Use your own pressure tank or order one of the Grundfos GT-tanks that make a perfect fit for your booster system. The pressure band is approximately 1 bar. When the system has been connected to the pipework, it is all a matter of inserting the plug into a power supply socket, and the system is operational.
