- 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
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.
- 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
