Multistage Centrifugal Pump

A centrifugal pump uses a rotating impeller to impart velocity to fluid, converting kinetic energy into pressure energy. In oil & gas operations, multistage centrifugal pumps like the QD280-43×6 are specifically designed for high-head applications requiring continuous and stable performance.

The pump features a robust multistage design with six impellers, allowing it to achieve high discharge pressures while maintaining excellent hydraulic efficiency. Manufactured using HT250 cast iron, ZG500 alloy steel, and EN X20Cr13 fasteners, the pump provides outstanding mechanical strength, corrosion resistance, and long operational life.
