misunderstanding in plan 52 + 53 + tandem seal !!
(OP)
hi good day for you
actually i fell tired in understanding tandem seal arrangement and plans
*does tandem seal used as pressuerized and non pressureized seal ?
*some manufacturers used plan 53 with tandem seal
on other hand i read in some books plan 53 used in conjunction with double back to back seal whet is right ?
* when do we must used plan 52 , why dont we used plan 53 all the time to prevent any leak , why there is a plan 52 from the base is it related to avoide diluting for examble ?
finally
*if there is any leak from the primary seal in the tandem seal in plan 52 we know the leak will mix with the buffer fluid its mean what will buffer now the dangerous pumped product , how can we Separate the buffer fluid from dangerous Product?
according to my information the buffer tank must be vented to flare how ?
thank you all
