Description
  • Optimized labyrinth design for high efficiency and good rotordynamic behavior
  • Shaft forged with low Length to Diameter (L/D) ratio for stable operation without critical speed problems and reduced vibration levels
  • Radial grooves provide increased radial stiffness, reduced effect on rotor tilting, and good rotor dynamic behavior
  • Swirl break at balancing piston to maintain rotor stability even when internal clearances are worn
  • Optimized shaft sealing design with jacket cooling and mechanical seal: pre-warming not required

Main applications

  • Main boiler feed in thermal power stations
  • Start-up boiler feed in thermal power stations

Main design features

  • Double suction first stage available in small sizes
  • Impellers are shrunk on, have keys for torque transmission, and use split ring for thrust loading
  • The pumps are provided with balance drum with shrunk on thrust collar, and oil press fit to avoid damage during transient conditions
  • Four-lobe journal bearing provides high stiffness and damping to minimize shaft movement
  • Fully rated double-acting, tilting-pad thrust bearing
  • Shrunk on coupling with oil press fit, parallel stepped or taper fit.
