Well, I sure don't want to be accused of bad mouthing anything Bob sells, so this places me in an uncomfortable position. But from a purely theoretical point of view, here is how I see it. The FloJet air diapraghm pump is very attractively priced! Basically, it is 2 pumps placed together, to acheive the desired flow. This mean 4 diapraghms are doing the work of 2 vs the Yamada and All Flow. Just as a bigger woofer makes more bass, a larger diapraghm makes more flow, all things being EQUAL. It is real simple Bore times Stroke equals Displacement. Air and Liquids are BOTH Fluids, so the same rules apply. Now, when we have a small bore(diapraghm), to make it displace as much as a larger one, we need to increase it's Stroke!

This means the diapraghm must travel more then a larger one, to displace the same amount of Fluid. So, in an absolute sense, a Larger air diapraghm pump is "better", since the larger diapraghm moves less.

This is the THEORY guys, but do not underestimate FloJet ! They are a huge company, and their pumps were computer modeled for long life. And remember, a small block Chevvy has a shorter stroke then a Big Block, yet lasts a longer time!

In the final analysis, I think it all depends on WHO you feel comfortable buying from. Bob has been known to have a few mistakes that were not his fault in the past, but has Always taken care of his customers. That has got to mean something. For years, in Seattle, I always bought Subaru's, just because of the great service from my local Subaru Dealer! I don't think you can go "wrong" with any of the 3 pumps, and what is better is a matter of opinion. I drive a new Ford F 150, so it is "the best"

My friend drives a new Silverado, so it is "the best".  I could be happy with any of the 3 pumps mentioned, as far as Poly Pumps goes. Now Kevlar, that is better, but bring your checkbook. The 1/2 inch Kevlar yamadas I use are 700 dollar pumps yawn

 

 



How many roofs did your pump last through

 

 




WE are getting from 6 to 8 months of use average out of our unrinsed Pumps before it is rebuild time. But we really use our pumps a lot. Usually the diapraghms go out, and this is normal wear and tear for any diapraghm pump. Every now and then an air valve will get a little cranky, but a shot of WD 40 in the air line, and it is good to go.

I put a flow jet on my trailer today. I didnt have a whole lot of time to fool with it but it does out shoot the all flo. Id say by 7-10' max. My yamada is wore out and needs rebuilt but itll hang real close with those two.

I bought one of Bobs pumps and hooked it all up on Friday. I have a Northern 5.5 compressor. Hooked it up and tested it by shootintg water all over the place like a maniac. This replaces my 12v Fatboy and it is a remarkable improvement. The flow jet is disturbingly light weight and made in China. At 80psi it seems to run effortlesslty. I bought Bob, not so much the pump He swears by its performance. First roof cleaning Wednesday and I'm excited to use it.

I have a Fat boy that I've had all year and no problem. I have the 3/4'' ag hose for the supply line and 250' of 5/8 hose on the reel. I rinse every night. The only problem was blowing the poly hoses I was useing them.
