Tank to tank pumping
Tank to tank pumping
(OP)
I want to completely drain a 1000 litre open tank to a 1200 litre holding tank and then refill.
The holding tank is above the open tank so would like to use a centrifugal pump. Can i use the holding tank extra capacity to create a pump priming circuit? When the open tank is empty (or nearly) to start recirculating the holding tank - keeping the pump primed?
If possible - would be great to use the pump to refill?
Bit of a speculative P&ID attached
Any thoughts most welcome. Thx

RE: Tank to tank pumping
on a side note (and not really related to your problem): but if you're looking to keep prime on a pump look into a self priming pump like the goulds 3796.
btw the attachment doesn't work.

I can not place a level sensor in the open tank.
I wanted to see if it were possible to use an existing centrifugal pump rather than self priming.
Have tried to upload a different P&ID attachment.
RE: Tank to tank pumping
completely draining a tank with a centrifugal pump isnt the best idea, since you will be going through pump seals after each few times you empty the tank if you dont operate it correctly. but i think this will work for you.
