Model 50 Duplex Basket Strainer, 10" to 18"

Iron or Bronze - Flanged

Overview

Duplex strainers remove damage causing particulate matter from the process media, and never have to be shut down for cleaning…the line can run continuously. When one strainer basket becomes full, flow is switched to the other. The first basket is removed, cleaned and is ready for use again.

These large size strainers use synchronized butterfly valves to switch the flow from one basket strainer chamber to another and never cause the flow to be shut off. Operation is quick and easy with the large, easy to use hand wheel…a few turns and the flow is diverted and the out of service basket is ready for cleaning.

This unique Hayward design has a straight through flow path that results in a very low pressure drop across the strainer. Another advantage of this Hayward design is that it is very compact and has a smaller profile than similar size strainers. Pleated (convoluted) type strainer baskets are used to increase the straining area while reducing size and weight of the basket and are a standard feature.
