Hi all
I've problem with choose suitable mesh for suction pumps strainers
Strainers will be working with aromatics hydrocarbons (stabilized reformate) in different temperatures (from 45 deg C to 140 deg C)
Have You ever seen any articles of adequate mesh selection or have any experience?
Best regards

Your best bet is to run some trial and error type of tests. Call somewhere and ask for samples of wire mesh of different sizes or even order an assortment.... as seen here for sale http://www.bwire.com...th_swatches.htm ..... and go from there in deciding exactly which mesh is going to be the best for you to use.

Good Luck though,

See attached general guidlines - it's more on strainer selection than Mesh size, but the best I could find. Mesh size should be selected based on what maximum size particle the downstream equipment can handle. If all you're worried about is protecting the pump from relatively large particles, i'd suggest 30 Mesh is acceptable for most centrifugal pumps (but always best to check with manufacturer)which will stop particles > 0.5 mm. But you may have process equipment that requires more stringent filtration, maybe PCHE.

If you select a filtration size that is too small it's likely to block the strainer more frequently resulting in increased maintenance. You also have pressure drop across the strainer to consider. We often use Y--type strainers with 30 mesh for pump suctions, they're fairly cheap and compact. However if you're using a mesh with smaller gap size or anticpating a lot of debris then you might want to use a basket strainer.

Hope this was helpful.
