Bolted-Cover Strainers
Jamison Products offers Bolted Cover Strainers to meet all your needs, ranging from standard to multiple option features vessels.
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
Debris, weld slag, scale, and other contaminants can damage rotating equipment, restrict flow, foul instrumentation, and create avoidable maintenance work. Bolted cover strainers provide a maintainable barrier where access, basket retention, and application-specific options matter.
- Protect pumps, meters, compressors, and valves from line debris
- Support basket access for cleaning and inspection
- Provide options for vents, drains, DP connections, seals, coatings, and support structures
- Reduce risk of basket movement or bypass through Jamison Posi-Lock design options
