Pump type
PE 65-32

The PE 65-32 feedwater pump is a centrifugal pump designed to supply water to stationary steam boilers with absolute steam pressure up to 6.2 MPa (63 kgf/cm²). It is intended for superheated feedwater in thermal power plant boilers, as well as waste-heat boilers at power plants with combined-cycle and steam-driven units.

Feedwater Requirements:

  • pH 7–9.2
  • Temperature ≤ 438 K (165°C)
  • Free of solid particles

Climate Rating: UHL for moderate and cold climates, indoor installation, category 4 per GOST 15150-69.

Design Features:

  • Single-Case Sectional Multistage: High efficiency and reliability.
  • External Sliding Bearings: Improve operational stability and extend service life.
  • Thermal Expansion Compensation: Design accommodates free thermal expansion of rotor and stator elements without misalignment.
  • Flexible Rotor Shaft: Diameter-to-length ratio up to 1:20 ensures durability; strict quality control is required.
  • Hydraulic Foot (Hydropad) for Axial Load Compensation: Balances axial forces for smooth operation across all operating conditions.

Operational Requirements:

  • High reliability and efficiency
  • 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, continuous falling head curve
  • Ease of assembly, disassembly, and maintenance

Drive and Efficiency:

Most commonly driven by an asynchronous electric motor with frequency converter.

  • Nominal rotation speed: 2960 rpm
  • Overall efficiency of pump + drive system: 66%
  • Nominal motor power: 110 kW

Dimensions and Weight:

Parameter Value
Pump Mass 1045 kg
Complete Unit Mass 2795 kg
Overall Dimensions (L×W×H) 1620 × 770 × 780 mm

Materials of Construction:

  • Pump Body, Sections, and Bearings: Cast iron СЧ20 (ГОСТ 1412) – corrosion-resistant and strong
  • Rotor Shaft: Heat-treated steel 40Х – high strength and wear resistance
  • Impellers: 25Л cast iron or stainless steel 20Х13 – durable and corrosion-resistant

Optional Upgrades:

  • Mechanical Seals: Replace traditional gland packing, reduce leaks, increase reliability
  • Bearings in Pumped Medium: Simplify maintenance and extend service intervals
  • VDS Monitoring System: Includes vibration, axial displacement, speed, and temperature sensors for predictive maintenance
  • Flow Path with Corrosion-Resistant Overlay: Stator made of carbon steel with anti-corrosion surfacing; rotor in stainless steel
