PRESSUREBOOSTINGSETS

GP pressure booster sets are small automatic systems with 2 or more pumps in parallel, designedand 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.

2GP units with two identical single-phase or three-phase pumps;• 3GP units with three identical three-phase pumps.For the GPEVM series, units with up to four pumps canbe provided on request. GPunits employ the following series of pumps: 1st)Small and medium capacity horizontalend-suction centrifugal models •multistage with threaded parts Compact series •single/dual-impeller with all stainless steel hydraulicparts, CDX-2CDX series•single/dual impeller with traditional hydraulic parts,CMA-CMB-CDAseries •water jacket cooled end-suction Multigo series •with standardized motor and coupling, all stainless steelhydraulic parts•with standardized motor and coupling, stainless steelhydraulic parts, except lower casing and seal plate in cast iron 2nd)Vertical multistage centrifugal models 3rd)Horizontal end-suction centrifugal modelsstandardized to EN 733 (former DIN 24255) •with all stainless steel hydraulic parts, 3M series •with traditional hydraulic parts, MD/MMD series There are two standard versions:•
