HPT high pressure barrel casing pump

Built to take on the pressures of your industry

The HPT is a pump specifically designed for boiler feed applications in thermal power stations. The pumps are optimized to provide high-efficiency operation over an extended period of time, thus reducing operating and maintenance costs.

HPT High Pressure Barrel Casing Pumps
Main benefits
  • Maximum safety due to double casing design. Pipework connections remain undisturbed during disassembly
  • High-strength barrel material to resist thermal shock
  • Full cartridge pull-out for rapid changeover
  • Design features that eliminate the need for pre-warming in most installations except on large size
  • Long operating life regardless of the operating mode
Main applications
  • Main boiler feed in thermal power stations
Main design features
  • Barrel design incorporates many design features resulting from Sulzer/EPRI research contract
  • Axial thrust compensation by balance piston to avoid damage during transient conditions
  • Fully rated double-acting tilting pad thrust bearing
  • Radial grooves for increased radial stiffness, reduced effect on rotor tilting, and good rotor dynamic behavior
  • Swirl break at balance piston to maintain rotor stability, even when the running clearances are worn

Applications
  • Boiler feed water and booster pumps
    Feed water pumps (FWP) pump the feed water from the de-aerator through the HP heaters to the boiler. The major characteristic of FWP is their high differential head.
