Basket Strainers

Second most popular Strainers are Basket or Bucket Strainers. Its name is derived from type of Screen used in these Strainers. These Strainers are popular due to its moderate to large free flow area through screen, longer shut down time, lesser pressure drop & suitability for coarse & fine filtration upto 50 Microns. They are commonly installed at suction to prevent debris from entering Pumps, Compressors & Rotating Equipment& Vessels.

Size : DN 25Nb to DN600.
Here debris is collected at bottom of screen. Clogged Screen can be cleaned by opening the cover & removing the screen from housing for cleaning.
Construction of Basket Strainers : Most popular is Fabricated construction due to its economy & ease of manufacturing. Smaller sizes are also offered in cast constraction.
We offer Cast Construction Basket Strainer up to DN 350 on demand . However they are bulky.
Rubber lined& PTFE lined Basket Strainers are offered for arduous application.
Size Range : We offer Size DN 15 to DN 600.
End Connection :

Flange End connection is widely used. Smaller size Strainers have socket weld or threaded connection. For High Pressure explosive, hazardous & gaseous service sometimes Butt weld ends are also used.
Pressure Rating & Standard : Flange End & Butt Weld End: ASME B 16.5 150#, 300#, 600#.
Threaded End: ASME B 1.20.1 NPT & BSPT- 800# & 1500#.
Material Specifications:

Advantages :
  • Low Pressure drop across Screen.
  • Screen Size is moderate to high. Dirt holding capacity is better. Hence Shut down time is longer.
  • Easy to open Cover & cleaning of Screen.
