Description

The axially split multistage centrifugal pump utilizes multiple impeller stages to progressively pressurize liquid, delivering high head and working pressure for demanding industrial applications. Its axially split design facilitates installation, maintenance, and overhaul, making it an efficient and reliable choice for large-scale fluid transport.

Main Technical Parameters:

  • Flow rate: Q = 7.2 m³/h to 1000 m³/h — suitable for a wide range of flow requirements, from small to large volumes.
  • Head: H = 90 m to 1200 m — delivers high heads for applications with significant conveying heights.
  • Operating temperature: ≤ 204 °C — stable operation at elevated temperatures, ideal for high-temperature media.
  • Drive power: up to 2000 kW — adapts to flow and head needs, ensuring efficient performance.

Structural Design:

  • Axial split: Pump body is split along the axis (fixed by bolts) for easy access, installation, and maintenance.
  • Multi-stage design: Multiple centrifugal impellers sequentially increase pressure and velocity, ensuring reliable high-pressure fluid delivery.
  • Centerline installation: Enhances operational stability and reduces vibration.
  • Side suction and discharge ports: Improves hydrodynamic performance and reduces flow losses.

Main Applications:

  • Pipeline transportation of crude/refined oil: Efficiently and reliably transports oil in petroleum pipeline systems.
  • Oilfield water injection: Maintains reservoir pressure and supports oil/gas extraction.
  • Refining & petrochemical processes: Transports raw oil, chemical liquids, and process fluids for continuous production.
  • Thermal power plant boiler feed water: Provides necessary pressure and flow for stable boiler operation.
  • Hydraulic recycling systems: Suitable for water treatment, circulating water, and other fluid recycling operations.

Features:

  • High efficiency & energy saving: Maintains high performance and reduces energy consumption at high pressures/flows.
  • High temperature & corrosion resistance: Operates reliably with hot and corrosive fluids due to durable materials.
  • Compact structure & easy maintenance: Axial split design simplifies servicing, reducing downtime.
  • High head & large flow: Delivers strong performance for high-pressure transport needs.
  • Stable operation & low noise: Precision design and symmetrical impeller layout ensure quiet, smooth operation.
