Max. Allowable Differential Pressure

[mggyi2006]

Dear Professionals,

Can u help me out how to decide max. allowable differential pressure of strainer for Data sheet in additive injection system?

I would think that this is a "* Vendor to specify", and is based on when the basket / screen will fail (or some margin below). I would suggest that this is a carry over from a filter datasheet where manufacturers have a recommended dirty pressure drop and you do not need to get too worried about it.

Is this supposed to be a spec for telling the vendor how big to make the screen wires? No.

Specify the design flowrate and what pressure drop you are willing to allow at the strainer before it starts to cause unacceptable losses of process capacity.
