Gas powered pump

[Tony Shelton]

Why does everyone use battery powered chemical pumps and not gas powered? Is it the rpms? Can't it be geared down?

Is there any use for something like this?

In what application Tony?I have a gas powered pump for roof cleaning,but I down stream chems for most anything else.I rarely use my xjet anymore and use a pump sprayer even less frequently.

I'm talking about oxalic or caustic over larger areas (as opposed to a pump up sprayer) Also looking at the possibilities for coil cleaner.
I was just wondering if there was a reason everyone always talks about battery pumps when it seems gas powered would be a more reliable method of delivery.

Down streaming for me is easier since the chems can be mixed at higher concentration then using the DSer to dilute to the final ratio.

That thing looks very cool. It all depends on the application I think. With a concentrated soap around doors and windows less flow is more useful. That looks like its more for hosing something down than applying a controlled amount. I've found the battery pumps (shurflo) to be very reliable. I guess that rig would be like downstreaming a mix as compared to applying a concentrate. I think I spray around a gallon a minute full strength and it covers about the speed I can walk.

Do you know how to order from the factory in China? I would like to go in on a container load of go-karts, quads, dirt bikes etc and pick them up in Long Beach.

Do a google search, and let it be known that you are interested in a container. They will contact you.

You have any requests?

How about these gas engine powered backpack sprayers!?

Bob at PressureTek was building some Chemical Bobcat pumps which were like a weedeater engine with a Delavan pump head. He only mad them for a short time but stopped due to the insurance liability I think.

It was a great idea and several guys bought them and I think they are still working.

I am not sure how much hose you can pump through with those smaller pumps but I had 200' of 3/8" hose a while back when I was running my FloJet pump that was 110 volt so I had to use a generator. The specs were 95psi at 1.6 or 1.8gpm, not a whole lot but it would get the job done at a good walkable speed.

I think that part of why they lasted me 1.5 years is that the pressure was higher for that much hose, if it was like 60 or less psi it might not have lasted as long.

I am not sure if it would go 300' or not but it always did 200' of the 3/8" hose.

Back to the gasoline powered pumps, it is probably the speed issue, you would have to run a gear drive to slow it down or maybe run it at higher than idle and have a pump head that would attach to it easily.
