AOD Pumps in Parrallel
AOD Pumps in Parrallel
(OP)
I need to pump a liquid with a viscosity of 4000cp out of a mixing tank to a holding tank. It is about a 60' vertical then a 15' horizonal run from the bottom of the mix take to the top of the holding tank. The existing pipe is 4". Using one AOD pump it would take a little less than an hour to transfer 47,000lbs of material from the mix tank to holding tank (95gpm). My questions is, could I replace the one AOD pump with two AOD pumps in parrallel to decrease my transfer time? And if so could I stick with the existing 4" pipe?
Material properties:
Viscosity 4000 cp
Density 13 lbs/gallon

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

May I suggest an electric driven facsimile of the AOD pump? Google for Abel Pumps.
Good luck,

If you could pair the shuttle valves of the two pumps such that one is on suction stroke while the other is on discharge stroke, you might get some extra capacity out of the existing piping system. I don't know of a pump mfg who makes an AOD pump like that, nor am I aware of any obvious way to do that with the pumps we buy.
But if both pumps are set to stroke at random or in sync, all you'll do is increase the peak flow and hence the frictional loss. You'll get more flow, but nowhere nearly double.
