Multi-stage, horizontal, radial split; foot or centerline mounting, support at both ends. The CFD fluid analysis software system is used to design high-efficiency hydraulic power, and the special mid-stage application makes the overall efficiency of the pump reach the international leading level. Forged pressure parts, precision casting flow parts, special friction ring surface treatment process, reasonable bearing arrangement and lubrication ensure the safety and reliability of the pump and long-term operation requirements.
