G MULTISTAGE CENTRIFUGAL PUMPS 

APPLICATIONS:
G serie multistage centrifugal pumps are designed for trouble-free pumping for clear or slightly dirty liquids and used in: heating plants, waterworks and water supply plants, pressure raising plants, water and condensate circulation, fire fighting system, boiler feeding plants, high pressure washing, reverse osmosis. 

CONSTRUCTION:
The pumps are multistaged centrifugal with radial split casings. In all versions the supporting feet on pressure side are placed under the discharge body. For sizes up to 65 the base feet, on suction side, are placed under the first stage casing, to allow the rotation of the suction casing in any direction. For bigger sizes the base feet are placed under the suction body, the rotation of which is possible only upon request. The impellers are provided with balancing holes to reduce the axial thrust. The shaft is supported by grease or oil lubricated roller bearings. 

MAXIMUM OPERATING TEMPERATURE:
Standard execution: up to 120°C
With cooling chamber: up to 160°C
NOTE: for temperatures exceeding 160°C please contact our Technical Department.

MAXIMUM OPERATING PRESSURE:
On suction side: up to 25 bar
On discharge side: up to 64 bar
NOTE: for higher operating pressures, please contact our Technical Department.

TECHNICAL FEATURES:
Capacity up to 600 m3/h
Total head up to 400 m
Revolutions up to 3600 RPM
Pressure up to 64 bar
Flanges: suction side PN 16-25, delivery side PN 40-64 

VERTICAL MULTISTAGE CENTRIFUGAL PUMPS "GV" SERIES:
Vertical multistage centrifugal pumps "GV" series, standard configuration, with upper ball bearings support and lower bushing support. Besides the usual applications where high pressure is required, the vertical configuration is largely used in the marine field.
