Centrifugal Compressor 910-41-1СМП is one of the recent REP Holding developments featuring higher capacity and efficiency. Compressor 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
