DEFINITION AND USE OF THE PRESSURE BOOSTER UNITS
If the public water distribution system is inexistent or insufficient for correct functioning of the utilities, it is necessary to install a pressure boosting unit in order to guarantee an acceptable pressure and amount of water also in the most unfavourable points of use. The pressure boosting unit is applied every time the pressure must be increases or where the mains water must be pressurised. The GPs, EBARA pressure boosting units, are small automatic systems with 2 or more pumps in parallel, studied and realised simply and reliably to satisfy the most recurrent pressure maintenance requests in the water supply of condominiums, hotels, centres, offices, schools, auxiliary services in the industrial and agricultural ambit. They are distinguished for the construction strength, compactness, high efficiency and silence. The GP units are set-up for the membrane autoclaves or air pocket connection. Start-up of the individual pumps is caused by the activation of pressure switches, appropriately calibrated via an electric control panel. In the units controlled with electric control panel with INVERTER, as well as pressure switches, one of the pumps is started via the calibration of a pressure transducer.
