HGB, HGC

Product catalog summary

Product Overview: The document introduces the HGB and HGC high-pressure centrifugal pumps with double-flow entry, available in sizes 4 to 6. These pumps are designed for high-performance applications in power stations and industrial plants.

Fields of Application: The pumps are suitable for handling feed water and condensate in power stations and industrial plants, as well as generating pressurized water for various industrial applications such as presses, decorticators, descaling plants, and snow generators.

Operating Data: The pumps can handle capacities up to 320 l/s, heads up to 3400 m, and temperatures up to 200°C. They operate at suction pressures up to 30 bar and discharge pressures up to 340 bar, with speeds up to 7000 min^-1.

Design: These are horizontal, radially split, ring-section pumps with radial impellers and a double-flow entry. They are multistage pumps with metallic sealing faces and are fastened by tie bolts.

Technical Specifications: The document details various components such as pump feet location, bearing types and lubrication methods, balancing devices, shaft seals, nozzle orientations, and flange connections. It also describes the drive options, which include direct drive by electric motor, turbine, or combustion engine, and indirect drive through a gearbox or hydraulic coupling.

Materials: The document provides a list of components with corresponding material selections, including C-steel, Cr-steel, and cast iron for various parts like suction casing, delivery casing, stage casing, impeller, and more.

Selection Charts: The document includes selection charts for 50 Hz and 60 Hz operations, indicating the performance range of the pumps under different conditions.
