CN Radially Split, Diffuser Casing, Single-Stage Nuclear Pump
CN Radially Split, Diffuser Casing, Single-Stage Nuclear Pump
| Brand: | IDP |
|---|---|
| Description: | The Flowserve CN is a single-stage, high-speed pump featuring a rugged, diffuser-style barrel design. Designed to meet ASME Section IV Division 1 requirements, it incorporates a centerline-mounted, radially split casing and a double-suction impeller. This configuration ensures nearly balanced axial hydraulic thrust across the full operating range, making it ideal for demanding nuclear applications. |
The CN single-stage, high-speed pump features a rugged, diffuser-style barrel design. Designed to ASME Section IV Division 1 requirements as well as customer specifications, it also features a centerline mounted, radially split casing and a double-suction impeller. This design renders nearly balanced axial hydraulic thrust over the full operating range of the pumps.
CN Radially Nuclear Pump Applications
Nuclear Service
- Industries:
Power Generation
416 Stainless Steel Shaft is ground in steps to minimize stresses. It is then stress relieved in the vertical position to prevent warping.
Precision Cast Chrome Steel Impellers are secured to the shaft with keys and a shrink fit against a shaft shoulder.
Serrated Impeller Running Fits reduce the effects of rotor contact during system upsets or turning gear operation.
Suction and Discharge Nozzles can be provided in numerous configurations to accommodate plant piping layouts.
Robust Bearing System uses split sleeve tri-land hydrodynamic radial bearings to support radial loads. Axial loads are carried by pivot shoe thrust bearings.
Full 360-degree bearing housings are used (omitted: “on the CN pump”) for added rigidity.
Advanced Sealing System is a controlled leakage design that employs a fixed serrated bushing over a straight shaft sleeve at each end of the pump.
