This Policy is currently under Development for questions contact the Area manager .
The purpose of this procedure is to establish the minimum requirements for the installation or replacement of the PSC coupling on electric motors driving LeRoi model compressors as laid out in this procedure.
This procedure applies to all skids equipped with the PSC Coupling on electric drive units that are currently in service in the Field, Test Loop, at a Repair Shop, or in Storage Yards. Flogistix Service Technicians will perform the installation or replacement as required according to instructions outlined in this procedure.
Before any work is performed a JSA needs to be done according to Flogistix procedure along with any Customer requirements before any work is started.
When installing the PSC Coupling it needs to be installed correctly per the attached PSC Quick Reference & Troubleshooting Guide.
The following Couplings are the sizes that Flogistix uses. They are all the 57 Series Coupling
PSC Coupling Flogistix Model
PSC 57-516 VRX15, FX8V25, FX8V10,VRX7
PSC 57-696 FX10V75, FX12V75, FX12V125
PSC 57-906 FX17V150, FX17V200, FX20V300
Due to the fact that some couplings have the same motor shaft size but the compressor shaft size may be different. The NetSuite Part Number will be different for each coupling set
