APPLICATIONS

G serie multistage centrifugal pumps are designed for trouble-free pumping for clear or slightly dirty liquids without solids in suspension and used in: steel industry, waterworks and water supply plants, pressure raising systems, water supply systems, fire fighting systems, boiler feed water systems, 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

Up to 180°C with special arrangements.

MAXIMUM OPERATING PRESSURE

On suction side: up to 25 bar
On discharge side: up to 64 bar

Capacity up to 600 m3/h
Total head up to 400 m
Speed up to 3500 RPM
Discharge pressure up to 64 bar
Flanges: suction side NP 16-25, delivery side NP 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 typically used in the shipbuilding industry.
