3. Duplex Continuous Flow Basket Strainers

 

Duplex Strainers are designed for applications where flow cannot be shut down to service the strainer screen. Change over is accomplished by use of butterfly valves

This arrangement provides a bubble-tight shut off between basket chambers, essential for use in negative head pump suction systems.

 

Specifications : 

 

• Size Range: ¾" - 20"

• Pressure Class: 125 LB - 150 LB

 

Features : 

 

Duplex basket strainers in sizes ¾” – 6” have knob type covers for tool free ease in basket removal. and also designed so the handle is over the in-service chamber allowing for easy cleaning and removal of the off-duty chamber basket.
