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 installations in a straighforward, reliable manner.  GP units are supplied ready for connection to diaphragm and air-cushion pressure vessels and those 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 panel.  In units controlled with a control panel equipped with an inverter (VLT), in addition to pressure switches, one of the pumps is started by setting a pressure transducer.

There are two standard versions:

• 2GP units with two identical single-phase or threephase pumps;

• 3GP units with three identical three-phase pumps.

For the GP EVM series, units with up to four pumps can be provided on request.
