GRUNDFOS CMB5-37PT AUTOMATIC PRESSURE BOOSTER PUMP [ A-C-A-G-P-B ] 0.67KW | 1PH | 99953852 | 18L TANK | 97L/MIN [ CM537PT ]

CMB 5-37 A-C-A-G-P-B

The Grundfos CM Booster PT 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 pressure tank, and a pressure switch assembled into one unit. The system is supplied ready for use, with preset start pressure and corresponding tank precharge pressure. The pressure band is approximately 1 bar. The system is simple to install. 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.

Features:

• CM pump
• Pressure tank to minimize the number of pump starts
• Motor protection (single-phase only)
• Automatic operation.

The Grundfos CM Booster PT is mainly used for agricultural and light-commercial water supply and similar water installations where minor leakages can be expected.
