Duplex Basket Strainer Manufacturer in Canada
A duplex basket strainer is a continuous-duty filtration device designed to remove solid contaminants from liquid process streams without interrupting system operation. By allowing one strainer chamber to remain online while the other is isolated for cleaning, duplex basket strainers ensure uninterrupted flow, protect downstream equipment, and maintain process reliability in critical industrial systems.
SVR Global is a trusted Duplex Basket Strainer Manufacturer and Supplier in Canada, supplying engineered strainer solutions for oil & gas, power generation, chemical processing, marine, and water infrastructure projects. Our duplex basket strainers are designed for continuous operation, high dirt-holding capacity, and reliable performance under demanding pressure and temperature conditions.
With proven experience supporting EPC contractors, plant operators, and system integrators across Canada, SVR Global delivers duplex basket strainers that meet stringent project specifications and international quality standards.
What Is a Duplex Basket Strainer?
A duplex basket strainer consists of two basket strainer chambers connected through a diverter or changeover valve. This configuration allows flow to be switched from one chamber to the other without shutting down the process. While one basket remains in service, the offline basket can be cleaned or replaced, ensuring continuous filtration and reduced operational downtime.
Duplex basket strainers are widely used where process continuity is critical and system shutdowns are costly or impractical.
Duplex Basket Strainer Applications in Industrial Systems
SVR Global duplex basket strainers are used across a wide range of industrial applications, including:
- Continuous filtration in oil & gas pipelines and process units
- Protection of pumps, compressors, and control valves in power plants
- Solids removal in chemical processing and petrochemical systems
- Seawater intake and cooling water systems in marine and offshore service
- Filtration in water transmission, treatment, and industrial utility networks
These applications require strainers with high flow capacity, low pressure drop, and reliable changeover mechanisms.
Types of Duplex Basket Strainers
SVR Global manufactures and supplies multiple duplex basket strainer designs to suit different operating requirements:
Manual Duplex Basket Strainers
Equipped with a manually operated changeover valve. Suitable for applications where periodic monitoring and manual intervention are acceptable.
Automatic Duplex Basket Strainers
Designed with motorized or pneumatically actuated changeover mechanisms for automated operation in continuous and critical process systems.
High-Pressure Duplex Basket Strainers
Engineered for high-pressure oil & gas and power generation applications where mechanical strength and sealing integrity are critical.
Temporary and Fine Filtration Duplex Strainers
Supplied with interchangeable baskets for coarse or fine filtration depending on process media and cleanliness requirements.
