1 inch female IPS connections - 5 foot power cord - 1 phase - Three impellers - Integrated frequency converter - Suitable for water supply in domestic applications. Thanks to the integrated speed controller, the booster keeps a constant pressure in the pipe system. A pressure sensor monitoring changes in the water consumption, will signal to the speed controller to change the motor speed to adapt the performance to the new situation. The optional inlet pressure switch prevents the pump from operating in case of low inlet pressure. The CMBE Booster consists of these components: CME pump with integrated frequency converter, 5 way fitting with non-return valve, diaphragm tank, pressure gauge, and pressure sensor
