GP-GPE

Pressure Booster Sets

EBARA GP pressure booster sets are small automatic systems with 2 or more pumps in parallel, designed and built to meet the most common requirements in terms of water pressure maintenance in residential, commercial, industrial and agricultural installation in straightforward, reliable manner. GP units are supplied ready for connection to diaphragm and air-cushion pressure vessels and with an air feed. The pumps belonging to the individual unit are started by the activation of suitably set pressure switches by means of a control penal. In units controlled with a control penal equipped with an inverter (GPE), the pumps started by setting a pressure transducer. The GPE unit is designed to work with pump controlled by a frequency converter (inverter).
