Strainer on cooling water

Strainer on cooling water

Strainer on cooling water

(OP)
Hello everybody,
In my refinery, because of lack of area, Basket filter at suction of cooling water booster pump was dismantled. In place of this T type strainer (30") with mesh size 7 mesh was put but it is getting frequently plugged(every 4-5 hrs).Cooling water source is from sea water channel.
Pump flow rate (rated) is 5150 m3/hr
Currently we are operating with a 2.5 mesh screen.It seems that my 30" strainer is undersized. Please help me in deciding the suitable size of strainer required to overcome the problem.

Thanks all in advance

 

RE: Strainer on cooling water

This seems to be a good application for a self-cleaning strainer. There are a number on the market.

RE: Strainer on cooling water

I have used Orival's and also a self cleaning strainer by Hayward.  But I agree with fortsa that a self cleaner should be on the pump discharge.  Other than a screen, I don't favor a strainer on a pump suction unless it is force fed.
