Seal chamber pressure question
Seal chamber pressure question
(OP)
Hi folks. My question is in regards to an overhung API pump with closed impeller, wear rings and BALANCE HOLES.
I would like to ascertain if the pressure acting behind the impeller, in the area where the balance holes are located (adjacent to seal chamber), if it is only slightly above suction pressure. (assume no seal flush flow)
I am having trouble accepting the 25% of deltaP estimation for this particular type of impeller design...
