Multistage centrifugal pumps in horizontal and vertical arrangement
G series multistage centrifugal pumps are designed for the problem-free pumping of clear or slightly dirty liquids without solid particles. This type of pump is used in the steel industry, water treatment and water supply systems, pressure booster systems, water supply systems, fire fighting systems, boiler feed water systems, high pressure cleaning and reversed osmosis applications.
The type G pumps are multistage centrifugal pumps with radial segments. For sizes up to DN65, the suction side mounting feet are placed under the first stage housing to allow the suction flange to rotate in any direction. For larger sizes, the mounting feet are placed under the suction connection housing, the rotation of which is only possible on request. The impellers are provided with balancing holes to reduce axial thrust. The shaft is supported by grease or oil lubricated roller bearings.
Maximum operating temperature
The maximum operating temperature for this pump is 180 ° C in the standard versions available. On special request, versions are available that can be used on processes with higher temperatures.
Maximum working pressure
On the suction side up to 25 bar, on the pressure side up to 64 bar Vertical version type GV Vertical multistage centrifugal pumps “GV” series, standard configuration, with support for upper ball bearings and support for lower bushings. In addition to the usual applications where high pressure is required, the vertical configuration is usually used in the shipbuilding industry due to the very compact construction method.
