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 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
