Variable Delavan - anyone use it yet?
Permalink  
 


A variable output 12v pump by Delavan.  Anyone try this thing yet?  The 3.4 gpm version can be throttled back to .6 gpm, and the 5 gpm variety can be throttled back to .7 gpm.

I haven't used it. Northern Tools has them for $200. It might be worth the $15 for the 1 year extended Warranty replacement plan.

We may have found it's downfall during Talkshoe last night.  In the table above, look at the PSI at the higher flow rates.  Only 10 PSI at maximum flow.

It *could* have a use as an additional detail pump at the lower flow rates I guess.  Not worth the trouble for that I don't think.

Please do let us know what you find out after test driving one Bruce

Looks like I may have jumped to a premature conclusion - thanks Scott!  I'll do some additional reseach this evening.
