Structural characteristics

Spiral shell single-stage double suction centrifugal pump, supported at both ends of the horizontal centerline. API Definition Type: BB2

The inlet and outlet of the pump can be adjusted upwards or downwards as needed, and the discharge part can be equipped with radial guide vanes. This series is suitable for use as the main feedwater pump for nuclear power units, with a medium temperature not exceeding 200 ℃.

The pump is supported by sliding bearings for forced lubrication. The shaft seal is a mechanical seal.

The double suction impeller self balances the axial force, and the residual axial force is borne by the thrust bearing.
