horizontal high pressure multistage centrifugal pumps

horizontal high pressure multistage centrifugal pumps

horizontal high pressure multistage centrifugal pump is a kind of pump type that utilizes the principle of centrifugal force to pressurize step by step through multiple impeller stage segments to achieve high head output, which is mainly powered by the driving device to push the liquid flow in the pump body.

Description

Horizontal high-pressure multi-stage centrifugal pumps utilize multiple impeller stages, each providing a pressure increment, to achieve high-pressure liquid delivery. Well-suited for applications requiring large flow, high head, and high temperature, these pumps are widely used in oil refining, chemical, metallurgy, and other industries.

Main technical parameters:

  • Flow rate: 100 to 450 m³/h
  • Head: 400 to 3000 m
  • Working temperature: ≤ 380°C
  • Driving power: about 4500 kW

Structural features:

  • Double-case design: Radial split shell increases strength and stability; horizontal open core design reduces axial vibration and improves overall stability.
  • Multi-stage horizontal structure: Multiple impeller stages provide progressive pressurization and stable high head flow, designed for high-pressure environments.
  • Symmetrically arranged impeller group: Dual impeller groups ensure even flow distribution, reducing vibration and noise.

Features:

  • Wide high-efficiency zone: Adapts to various flow and head needs, ensuring efficient operation.
  • Good self-balancing axial force: Design balances axial force, reduces bearing wear and mechanical failure, enhancing operational stability.
  • Easy and fast maintenance: Modular, integrated design enables quick disassembly and maintenance, reducing downtime.
  • Safe and reliable structure: High-strength materials and precision machining enable stable operation in high-pressure, high-temperature environments.
  • High efficiency and energy saving: Delivers excellent efficiency, supporting modern energy-saving and emission-reduction requirements.

Applications:

  • Refining and chemical industry: Raw material feeding, high temperature/high pressure/volatile fluid transportation.
  • Raw material feeding pump: Used in chemical, oil refining, and other industries for transporting raw material liquids (e.g., oils, chemicals).
  • High-pressure conveying: Equipment requiring fluid transport under high temperature and high pressure, including petroleum processing, fertilizer production, metallurgy, and more.
