Cast Bronze Duplex Strainers

Continuous Flow Basket Strainers for Water & Marine Service

We offer cast bronze duplex strainers from Eaton and Keckley. Titan does not currently offer duplex strainers in bronze. Both Eaton and Keckley provide a ball-valve style diverter for the ¾" through 4" sizes.

 

The main difference between brands is the sealing seat. Eaton uses an elastomeric (Buna or Viton) seat for a tighter seal. Keckley uses a metal-to-metal seat, so slightly higher leakage into the isolated chamber is expected.

 

The ball-valve diverter is simple to operate — rotate the lever 180° to isolate a basket chamber.

 

5"–8" sizes are available only from Eaton and use a tapered plug-valve diverter. This design requires an extra step: lift the plug off its seat with a jack screw, divert the flow, then reseat. The metal-to-metal seal can be advantageous with aggressive fluids.

All of these cast bronze strainers are rated 225 PSIG @ 150°F. Flanged versions have Class 150# FF connections. For higher-pressure applications, use higher-rated simplex strainers with stainless steel diverting valves to create a duplex arrangement.

 

Use the calculator for both Eaton and Keckley models. Select connection size, enter flow rate (GPM), adjust specific gravity and viscosity if needed, then update. Target a clean differential of ≤ 2 PSI.

 

Which Duplex Strainer Design is the “Best”?

 

Because performance is nearly identical between the two brands, the decision usually comes down to pricing and lead time. We can quote both options.
