Berkley vs. Dominator pumps (intake, suction piece, bowl, ect.) can anyone give the facts, ok, opinions between the two. Is one a better performer?

The dominator is water lubed at the end of the shaft and I think the wear ring shoulder is a little wider on the Dom , otherwise identical . Ah , who am I kidding , I dont know .

The two Basic jets (12 jg/c Berk and Dom 12s) are very similar and many parts interchange between them  Some diffences like Omar said are wear ring shoulder size and design and the grease slinger behind the frt bearing . With the exception of the very early Berks (12 A&B) ,all Berk 12j  models including the E&F use virtually them same parts for repair . Dominator has "morphed" periodically over the years ,making changes to wear ring OD sizes and designs . Rebuilding the large number  jets as we do find there are "pitfalls" and its critical ,for example on Dominator to know serial #s for parts replacement accuracy. Omar is also correct on the "water lube" brgs on early Dom jets , now they have a snap ring retained double greasable seal vs Berk which uses a 90 wt oil reservoir. Lots of other jets (Aggresor, Legend A/T,Bayjet) and thier parts will also "swap" between each other but sometimes have fit and tolerance issues to be aware of sometimes requiring modifcations, lathe and mill work . Most of these Jets will all bolt to the others suction pieces (even Bayjet with some work ) As far as Pure strength goes ,my weapon of choice among them is always Dominator for its casting design and thickness on the suctions and bowls . Dominator/AT also is a company who is always "moving forward" working on new products and improvement , we use/install alot of the Dominator HP intakes and although the desing is not all that much diffenrent than the original Berk we find it a beautiful piece and "cake to install and set up . A Dominator 12s with a 17-4 shaft and Stainless impeller with hold up to Mega HP with very few other Mods . More info if you need or want it Tom@JBP

hey tom! yeah i believe i have the older 12s on my nordic cruiser...it has the 3-bolt inspection cover, and that 'spine gusset' along the top of the suction piece. is it possible to toss an aggressor bowl onto the dominator suction piece and fit the impellar? no reason, just curious  ;D

Reid depending on "Vintage" it could be a direct bolt up BUT Dominators and AT Impellers have "rear stuffer rings" cast in however the Aggressor bowl does not have this "stuffer  area machined to accept same (they "stuff " differently) . You'd have to make an Impeller change or mill off the ring or??? all of these bowls, suctions and impellers etc will "interchange" to some degree but not always without some "mods"

note the "ring" on the back side if the 'Impy"
