HPT high pressure barrel casing pump
HPT high pressure barrel casing pump
Built to take on the pressures of your industry
- 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 boiler feed in thermal power stations
- 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

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.
