We offer (6) models of cast 316SS simplex strainers from three manufactures for 3/8" to 16" size pipelines. Please use our differential pressure calculator to compare the relative performance of each model in addition to reviewing the specific features of each using the catalog page and drawing link table below.
The first step is to select the strainer size, input the maximum flow rate in gallons per minute (GPM), select the desired particle retention and, if your fluid isn't water or "water-like", input the specific gravity (Sg) and viscosity (SSU).
The calculator will automatically update the theoretical clean differential pressure drop along with the maximum flow rate with a perforated basket based upon the maximum recommended 2 PSIG clean differential pressure. The flow coefficient value (Cv) is also provided for reference for calculations of overall piping pressure drop.
Your strainer should have a clean differential pressure drop ≤ 2 PSIG and the basket cleaned once the differential pressure increases by 5 PSIG. Assuming a consistent particle load, a lower initial (clean) differential pressure may equate to longer time between basket cleaning; it also means that it can handle a higher flow rate.
In some cases your flow rate might make one particular model more appropriate than another. There are also different features, such as bolted covers vs. quick-opening covers (requiring tools or not to access the strainer basket for cleaning). If it is a hot, high pressure or otherwise dangerous fluid, quick basket chamber access is not a desirable feature!
When the designs and performance are very similar it often boils down to pricing and lead time.
We suggest using our strainer inquiry form which will provide us with all the design criteria to suggest the most appropriate strainer for your application; we typically reply within the hour or certainly be the next business day. You may also call 908.362.9981 or send an email for a prompt reply to all of your questions.
