Duplex Strainer

For uninterrupted Flow we offer Duplex Basket strainers. Duplex Strainers have two housing. At a time one Strainer is in operation while second is kept isolated & kept ready for next Cleaning Cycle. When Screen of one Strainer is clogged, flow is diverted to next housing through 3 Way Ball Valves or Butterfly Valves. Cover of Clogged housing will be opened, Screen is Cleaned, reinstalled & kept ready for next Cleaning cycle.

Construction :

Strainer Housing is made from Fabrication. While 3 Way Ball Valves & Butterfly valves are Cast Construction.

Size Range : DN 25 to DN 450.
For Smaller size DN25 to DN100 we recommend 2 no. 3 way Ball valves, while for DN150& above size we recommend 4 No, Butterfly Valves.

Fabricated Simplex Basket Strainers

Being a member of the simplex basket strainer, fabricated simplex basket strainers have a basket shaped design with huge capacity of storing debris. Made up of stainless steel or carbon steel, this type of strainers has a slant top basket design. The design helps the flow of fluid technically because the slant top maintains low pressure drops. When it comes to the weight, fabricated simplex basket strainers weigh lesser than other basket strainers. Due to low weight,labours find it easier to remove the slant top for cleaning purposes.
