3GP are EBARA booster units with three identical three-phase motor-driven pumps. The 3GP Ebara pressure booster sets, in standard versions, can be used for residential, commercial, industrial and agricultural applications, namely for: water lifting or handling, cooling, heating, irrigation, washing systems. The liquid carried can be: clean water, drinking water, rainwater, well water, mixed water, provided it does not contain solids or fibres in suspension and is free of aggressive chemical substances. Units must be installed in a shelter of some kind and protected from the elements and frost. •Temperature of water carried in the range 0 to 50 °C (depending on the kind of pumps installed). • Ambient operating temperature in the range 0 to 40 °C at an altitude of no more than 1,000 m above sea level. • Relative humidity max. 50% at +40 °C. NB: it is worth remembering that suction lift (installations with liquid source lower than pump) decreases as altitude and temperature increase. These characteristics, based on the pump’s NPSH, must be allowed for when sizing the system so as to avoid problems such as cavitation or insufficient efficiency: the NPSH available in the system must be greater than the NPSH required of the pump.
