Pump type
PE 100-32

Centrifugal feed pumps PE 100-32 are designed to supply water to stationary steam boilers, with absolute vapor pressure up to 6.2 MPa (63 kgf / cm²). Feed water should have pH 7-9,2, the temperature not more than 438K (165 °C) and should not contain solid particles.

Pumps are manufactured in a climatic category of a moderately cold climate – they are designed for macroclimatic regions with temperate and cold climates, placement category 4 – operation in rooms (volumes) with artificially controlled climate conditions.

Purpose and Application

The PE 100-32 centrifugal feedwater pump is designed to supply superheated water to stationary steam boilers with absolute steam pressure up to 6.2 MPa (63 kgf/cm²). It is used in thermal power plant units, as well as in waste-heat boilers at power plants with combined-cycle and steam-driven installations.

  • Maximum Flow: 100 m³/h
  • Maximum Head: 330 m
  • Allowable NPSH: 4 m

Design Requirements

  • High reliability and efficiency
  • Free thermal expansion of rotor and stator without misalignment
  • External tightness and absence of internal leaks
  • Long service life: 15,000–30,000 hours with proper maintenance
  • Protection against backflow
  • Dynamic stability across all operating ranges
  • Smooth, continuously falling head curve
  • Ease of assembly, disassembly, and maintenance

Drive and Efficiency

  • Usually driven by an asynchronous electric motor with frequency converter
  • Nominal rotation speed: 2960 rpm
  • Overall efficiency of pump + drive system: 68%
  • Nominal motor power: 160 kW

Design Features

  • Single-Case Sectional Multistage: High efficiency and reliability
  • External Sliding Bearings: Improve stability and reduce wear
  • Thermal Expansion Compensation: Handles thermal expansion of feedwater effectively
  • Flexible Rotor Shaft: Diameter-to-length ratio up to 1:20 for strength and durability
  • Hydraulic Foot (Hydropad) for Axial Load Compensation: Balances axial forces across all operating conditions

Dimensions and Weight
