Description

The back-to-back impeller multistage centrifugal pump is a highly efficient and stable liquid transfer pump, adaptable to various operating environments. Its unique impeller design effectively balances axial force, making it ideal for high-pressure, high-head applications with excellent volumetric efficiency and low energy consumption.

back-to-back impeller pump Structural features:

  • Single-case radial split multi-stage centrifugal pump: Compact, easy to maintain and install. Radial split allows for simple impeller replacement or maintenance.
  • Back-to-back impeller arrangement: Naturally balances axial force, eliminating the need for complex balancing devices and simplifying design and maintenance.
  • Foot mounting: Suitable for diverse installation scenarios, ensuring stable operation.
  • Suction port at the side, discharge port at the top: Optimizes liquid flow and pump body compactness.

back-to-back impeller pump Main features:

  • Minimal volume loss, high efficiency: Reduced liquid flow resistance and internal loss for higher efficiency, lower energy consumption, and longer service life.
  • Handles media with small solid particles, gas, or high viscosity: Suitable for petroleum, oil, chemical media, and more.

back-to-back impeller pump Main technical parameters:

  • Flow rate: Q=12 to 180m³/h – wide range for medium to large scale liquid transport.
  • Lift: H=100 to 1500m – broad lift range for low to high-lift applications.
  • Working temperature: ≤105°C – suitable for medium-high temperature environments (oil, chemicals, etc.).
  • Driving power: up to 1250KW – supports large power for high load, high pressure conditions.

back-to-back impeller pump Advantages:

  • Excellent structural stability: Back-to-back impeller design effectively reduces axial force impact, ensuring stability under high pressure and flow.
  • Adaptable to complex media: Handles high viscosity liquids, those with solid particles or gas, broadening its industrial applicability.
  • Energy saving and efficient: High pump efficiency, low energy consumption and operating costs.
  • Easy maintenance: Simplified structure allows convenient maintenance and part replacement, reducing downtime.

Main uses:

  • Pipeline transportation of crude oil and refined products: Ideal for petroleum industry’s high-pressure, high-flow transport needs.
  • Thermal power plant boiler water supply: Delivers high-pressure water for continuous, efficient boiler operation.
  • Refining and petrochemical processes: Reliable fluid transport under high temperature and pressure.
  • Water supply installations: Provides stable high-pressure water for urban, industrial, and other systems.
