Water pump HPT

stainless steelcentrifugal

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. 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 Capacities - Up to 4,000 m3/h / 17,600 US gpm Heads - Up to 4,200 m / 13,800 ft Pressures - Up to 545 bar / 7,905 psi Temperatures - Up to 220°C / 430°F Discharge sizes - Up to 500 mm / 20 inches
