1. Features

This is a boiler feed pump for large-scale, 1,000-MW-class power stations and multi-stage turbine pump designed for high temperatures, the high pressures, and high speeds
This pump is comprised of a radially split inner casing freely supported with a robust outer casing and the axial thrust load caused by impeller arranged in one direction is balanced by the balancing device.

2. Main specifications

Horizontal-shaft barrel casing-type multi-stage turbine pump

  • Pump bore: φ400 mm × 4 units
  • Electric motor output: 19,700 kW

Pumps for thermal power stations, circulating water pumps

This is a circulating water pump for large-scale, 1,000-MW-class thermal power stations.
