Eaton Model 52 Duplex Basket Strainer

Iron or Bronze, Flanged, 10" to 18"

The Eaton Model 52 Duplex Basket Strainer has several important features and advantages for large size pipeline with high flow rates. Flow is switched from one basket chamber to the other by a pair of synchronized, high quality butterfly valves. This is the strainer to choose when you have a high flow rate application and a low pressure loss is critical.

  • Continuous flow - no shutdown for basket cleaning
  • Compact butterfly valve design
  • Quick opening covers
  • Perforated or mesh stainless steel basket
  • Positive shutoff
Available Sizes: 10", 12", 14", 16", 18"

For larger size pipelines with high flow rates the Eaton Model 50 Butterfly Valve Duplex Strainer offers several unique features and advantages over other large size strainers. Among them are low pressure loss, operator friendly quick opening covers that do not require lifting gear, a compact design with a smaller footprint than other strainers, and a special basket design to maximize time between basket cleanings.

Another important benefit of this design is a saving in overall size. It is more compact than other large size duplex strainers, which means less weight and a smaller profile. This can be very important when space requirements are tight. The design uses a unique strainer basket concept which results in a very large straining area. The basket is constructed by convoluting (pleating) the perforated sheet, thus increasing the available straining area while reducing the total basket size. The flow enters the basket from the side, not the top, resulting in a straight-through flow pattern. What all this means in service is a lower pressure drop and greater time between basket cleanings than would be possible with standard design baskets...saving time and lowering operating costs.

The butterfly valve assembly used to divert the flow from one basket chamber to the other is balanced so a minimum of effort is needed to switch the flow. There is a single hand wheel operator and it can be located on either side of the strainer if accessibility is a problem. There is an arrow on the top of the gear housing that indicates which basket chamber is in service and which is ready for cleaning. Quick opening covers make strainer basket changing or cleaning quick and easy. No tools or lifting gear are required to open them. This is a feature not often found on larger size strainers.

Unique Basket Design
The Model 52 incorporates a larger screening area by convoluting (pleating) the perforated sheet in the strainer basket, thus increasing the available screening area while reducing the total basket size.
