G-Series: GA

GA Model for Gas Compression

Interchangeable with Thomas AMR and TB Woods HSH with similar mass elastic characteristics

  • Alloy hub and stainless steel disc are standard

L-Series

Part-by-part interchangeable service parts for the Rexnord Thomas AMR/CMR and the TB Woods FSH/HSH disc couplings

Series 57

Drop-Out Spacer Disc Couplings

High torque density, lower mass, and better balance allow for much longer life of connected equipment

  • API 610 / 671 Compliant

Series 47

Drop-Out Spacer Disc Couplings

Same high torque density as the Series 57 couplings

  • Tunable stiffness for gas compression applications
  • API 610 / 671 Compliant

Industry Leading Features.

For Pump Packages

PSC has industry leading ease of installation.

  • Use of standard fasteners (instead of custom fasteners).
  • No balancing required up to 3,600 rpm for most sizes.
  • API-610 / API-671 compliant.

For High Torque / High Service Factor

PSC provides significant savings by providing high torque density which allows the use of a smaller coupling than the competition. 

  • Also, PSC has the capabilities to quickly customize our couplings for specific applications.
  • Rated torque up to 3.5 million in lbs.

For Gas Compression

PSC offers excellent alternatives to Rexnord AMR/CMR couplings or TB Woods couplings.

  • Due to the tunable stiffness, PSC’s disc couplings may be a good fit in packages where detuners can be avoided or where an elastomer coupling is recommended but a disc coupling is preferred.

For Custom Couplings

PSC’s product line is adaptable to a wide range of mounting requirements, material specifications, and performance needs.

  • The engineering team at PSC is eager to work with customers with quick turnaround and excellent value on custom couplings

PSC is changing the rules in custom flexible disc coupling market with outstanding value and the best in industry lead-times and service.

  • Superior product performance
  • Short lead-times standard
  • Industry leading torque density
  • Quick and easy installation
  • Comprehensive technical support

The technical team at PSC is eager to work with you to customize a solution for your flexible disc coupling needs. Whether you need a replacement for an existing coupling or a new design for a new application, the technical team at PSC is here to provide quick and comprehensive support.

Product Features

PSC’s Series 57/47 Offers Cutting Edge Product Features

  • Unitized disc packs simplify assembly and maintenance and provide improved performance.
