Automatic Strainer
/ Specifications

Automatic (Self-Cleaning) Strainers

Size

  • Available in sizes ranging from 2″ to 36″
  • Suitable for medium to large flow systems with heavy solids load

Connections

  • Nozzle arrangements can be:
    • Offset (standard)
    • In-line (top or bottom of the vessel)
  • Compatible with standard industrial piping connections

Body Materials

  • Fabricated using:
    • Carbon Steel
    • Stainless Steel
    • Assorted Alloys
  • Custom materials available based on application-specific needs

Filter / Mesh Options

  • Uses wedge wire filtration elements with slot sizes capable of handling:
    • Particles as small as 75 microns
    • Solids as large as 150 mm (6″ stones)
  • Cleaning is achieved via:
    • Spring-loaded blades (for larger particles)
    • Brush systems (for fine particles and slot cleaning)
  • Includes blowdown system for solids expulsion with minimal fluid loss

Advantages

  • Fully automatic operation minimizes manual intervention
  • Continuous flow without shutdown for cleaning
  • Handles wide range of solids – from fine particles to large debris
  • Efficient cleaning mechanism: spring-loaded blade and brush system ensures consistent screen contact
  • Blowdown system uses less fluid than backwash-type strainers
  • Reduces downtime and maintenance frequency
  • Customizable modular components (screeners, valves, gauges, controllers)

Power Ratings / Standards

  • Designed and fabricated in accordance with ANSI and ASME Sec. VIII, Div. 1 standards
  • Powered by a motorized mechanism with a fully automatic control system
  • Equipped with differential pressure gauges, flush valves, and controllers to manage self-cleaning cycles

Applications

  • Intake, process, and wastewater systems across diverse industries
  • Specific use cases:
    • Power Industry: Cooling systems, boiler wash, seal water
    • Pulp & Paper: Black liquor, white water filtration
    • Process Industry: Pumps, valves, heat exchangers, spray nozzles
    • Wastewater Treatment: Protect downstream systems from secondary effluent solids
    • Metal & Mining: Quenching, de-scaling, blast furnace cooling
    • Raw water filtration: River, lake, or seawater intakes
    • High-solids load fluids like wax, heavy oils, boiler slurry
