Flow Dual Basket Strainers are an innovative and economical alternative
to conventional Duplex Strainers. They are designed for applications
where flow cannot be shut down to service the strainer screen. Changeover
is accomplished by use of a handwheel operator on a buna lined (standard),
butterfly valve. This arrangement provides a bubble-tight shut off
between basket chambers, essential for use in gas or negative head
pump suction systems. Basket and flange sizes can be designed to
specific requirements by incorporating Sure Flow Fabricated Strainers.
Standard units are in Cast Iron with 125# ANSI flanged connections,
and Carbon or Stainless Steel with 150# ANSI flanged connections.
Many other options are available including higher pressure ratings,
automatic air vents, quick opening covers, special internal coatings,
backwash connections and more. We will help you select the best
Sure Flow Dual Basket Strainer for your specific application.
Sure Flow Model BDB bolted design Dual Basket Strainer is standard

Flow Model DB welded design Dual Basket Strainers are a very economical
alternative to standard uni-casting duplex strainers in cast steel
