Duplex Strainers

Jamison Products’ expertise is to design, manufacture, and supply duplex basket strainers that will meet all your requirements. The product supplied will be mechanically sound and will meet the design criteria and process performance.

With a multitude of applications, the strainer will either be custom-designed or standard cast to meet the operating conditions.

The Duplex Strainer can be offered with or without ASME ‘U’ Stamp and /or PED certification.

Jamison Products is involved in providing and testing strainers for the API Ad Hoc Committee on Flow Conditioning for Turbine Meters. This has contributed to the development of a new basket strainer, the Jamison Posi-Lock™, which is explicitly designed to improve process performance and prevent bypass caused by movement of the strainer basket in service.

THE CHALLENGE

Protect Critical Equipment from Debris and Filtration-Related Risk

Single-basket strainers can require shutdown or bypass arrangements when the basket needs cleaning. Duplex strainers help maintenance and operations teams maintain filtration continuity by allowing one side to remain in service while the other is isolated.

  • Maintain filtration while cleaning or inspecting one basket
  • Protect downstream components from debris and contaminants
  • Configure isolation valves to suit the application
  • Select custom or cast construction based on operating requirements
