Duplex Strainer

Duplex Strainers are ideal when the piping system cannot be shut down for basket cleaning. There are two screened baskets that trap debris, with a lever that switches between the two, allowing one basket to be cleaned with no interruption in flow - a benefit that is sometimes crucial. 

The duplex strainers (dual strainers) are available with threaded or flanged connections. Standard screens are provided for WOG (water, oil, gas) service, but other screens are available on request.  Different screens can also be used in each of the chambers, so that different batches can utilize the most appropriate screen.
