Right on. Figured they’d have more than one model available. Good to know its holding up ok.
So anyone used one of the gear driven units?
I haven’t. But in my little bit of research, here’s what I’ve found:
The gas powered diaphragm pumps bypass back to the mix tank, similar to a pw’er with buffer tank bypass set up. So this would mean it won’t work with a proportioning system (at least not without some serious refiguring).
I would recommend searching youtube for “Comet P36”. A lot of helpful videos there (and some junk, as well).
Fair enough. Idk why but there seems to be a terrible amount of bad info on youtube when it comes to this stuff. I’ve come to rely on this forum for more (but still not 100%) reliable information. I’ve watched some youtube on the subject.
And yeah, I had already thought about the lack of proportioner option. Sucks, but honestly was going to do batch mixing at first anyway.
I’ll do some more outside research and make a decision. Thanks for your time.
Rob Anderson’s videos seemed pretty solid, though not exhaustive.

I didn’t read but a few sentences of yours @JTRiley but you mentioned the Comet P36 and I believe you have a bit too much faith in that pump than you should. That manifold will not hold up like you think it will.
Yeah? What about the manifold wears out? (I am assuming you are talking about the discharge manifold). Have you used one or know someone who has?
Wears out??? lol it’s polypropylene it breaks pumping SH through it. I’ve gone through two. I may try the polyamide if I do any more commercial roofs

Pws sells the zeta pumps that work with proportioner now. How reliable are they I don’t know but what little bit I got to play around with it I thought it was incredible. Like a booster but much less space.
How many hours did put on them doing roofs?
I’d have to look at some paperwork to give you a better answer. But I only did about 40 roofs in 2018 but they took days to spray. So I’d say about 240 hours at 3% on each pump
That’s an interesting one, out of all the contractors I’ve spoken to that utilise these seem to get about 3 sets of discs replaced before any other problems usually about 300 hours between diaphragm and check valve replacements. They love them.
Those single cylinder GX’s love sending good vibes to anything attached to it. I would have liked to power one with a electric motor but I didn’t have the time
