Its low NPSHR and unique bag structure ensure efficient, stable operation with excellent sealing, making it suitable for a wide range of industrial applications, including high and low temperature conditions.

Features:

  • Low NPSHR (Net Positive Suction Head Required): Designed to minimize suction pressure, prevent cavitation, and maintain stable operation.
  • Bag structure: Unique bag design provides superior sealing performance and fluid transfer effect. Compact and easy to install, with adjustable installation modes for different environments.
  • Flexible installation forms: Supports both ground and vertical installation, adapting to varied application requirements.

Main Technical Parameters:

  • Flow: Q = 80 to 600 m³/h
  • Head: H = 40 to 800 m
  • Operating temperature: -180°C to +180°C
  • Drive power: approx. 630 kW

Structure:

  • Double-casing vertical multi-stage centrifugal pump: Withstands high pressure and high temperature environments.
  • Guide vane type inner casing: Enhances efficiency and stability, ensuring smooth fluid transport.
  • Side suction and outlet: Convenient for pipeline connection and system layout.

Main Uses:

  • Thermal power plant condensate transport: Ensures stable water flow in cooling systems.
  • Oil refining and petrochemical industry: Suitable for high temperature and pressure fluid transportation in refineries and petrochemical plants.
  • Low-temperature engineering: Effective for liquefied gas, liquid nitrogen, and other low-temperature fluid applications.

Key Features:

  • Double shell structure: Enhances pump strength, withstanding high pressure and temperature changes.
  • Low NPSHR and cartridge bag design: Reduces suction resistance and risk of cavitation, ensuring stable operation.
  • Wide adaptability: Handles high-temperature, high-pressure, and low-temperature environments for critical processes in power plants, refineries, and petrochemicals.
