Purpose and Application
The PE 100-53 centrifugal feedwater pump is designed for supplying water to stationary steam boilers with absolute steam pressure up to 6.2 MPa (63 kgf/cm²). It is ideal for thermal power plants, industrial boilers, and waste-heat boilers operating under high pressure.
- Maximum Flow: 100 m³/h
- Maximum Head: 580 m
- Allowable NPSH: 4 m
Design Requirements
- High reliability and long-term service
- 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 the entire operating range
- Smooth, continuously falling head curve
- Ease of assembly, disassembly, and maintenance
Drive and Efficiency
- Typically driven by an asynchronous electric motor with frequency converter
- Nominal rotation speed: 2980 rpm
- Overall system efficiency (pump + drive): 69%
- Motor power: 315 kW
Design Features
- Single-Case Sectional Multistage Design: Ensures high efficiency and reliability
- Rolling Bearings for Rotor Support: Provides stability and reduces wear
- Thermal Expansion Compensation: Handles thermal changes in feedwater efficiently
- Flexible Rotor Shaft: Diameter-to-length ratio up to 1:20, ensuring strength and durability
- Hydraulic Foot for Axial Load Compensation: Balances axial forces across all operating conditions
