910-41-1СМП Compressor

Centrifugal Compressor 910-41-1СМП is one of the recent REP Holding  developments featuring higher capacity and efficiencyCompressor 910-41-1СМП is designed for compression and transportation of associated gas. It is applied in assembly with gas-pumping units at booster compressor stations of the gas producing industry. The compressor design employs integrally-machined  axial – radial impellers with 3D blades,  the active magnetic bearing  system and dry gas dynamic seals. REP Holding established in-house production of electric drives and magnetic bearings under  S2M (SKF) licenses.

Configuration:

barrel type casing 

      - 4 compression stages (3 out of them with  axial – radial impellers)

      - volute outlet chamber

      - dry gas dynamic seals

      - active magnetic bearing

Integrally-machined  axial – radial impellers with 3D blades are innovative high-technology flow path elements shaped to significantly increase compressor efficiency (by 5%),  reliability and operational life .  Integrally-machined  axial – radial impellers also provide an expanded range of capacity and head characteristics, as well as reduced mass and overall dimensions of the design.


Main advantages:

- active magnetic bearing  system and dry gas dynamic seals

- standardized assemblies and parts

 reduced operational costs and the amount of additional equipment

- improved reliability of the design

- twofold operational life increase

- higher efficiency due to no mechanical losses

- unique capacity in the 16 MW power rating with final pressure no less than 3.0 MPa
