Recommend me a 30cfm piston pump

[FOXonthefarm]

Doing a build for portable 13hp petrol engine belt fed piston pump with micro tank housed in a portable frame. Big tank in separate frame.
Concept is throw both frames onto a car trailer and connect them together in situ to reduce lifting weight.
Someone please recommend me a suitable 30cfm pump. Occasional use it will sit around mostly but want a quality pump?

its all down to your budget, the price will reflect the quality

That looks real smart and clever but I’m lacking in both those areas, so looking for off the shelf units I can bolt down into a 3mm box section frame so I can quickly complete this build.
And move on to the next stage developing a cold bitumen pothole sprayer, converting a blasting pot to a pressure vessel to feed the cold bitumen to the top part of a Schultz under seal gun and have a parallel air line to spray the viscous liquid onto road surface (testing needed).

A 30cfm pump will not be easy to source and expensive.
You can easily find 14cfm pumps and just run 2 in parallel.
Not sure if your 13hp engine will be strong enough to run this.

You will need a unloader/governor valve if you using a petrol engine to power the air head.

This will add cost...

30cfm is big for small engine driven compressor. And I have owned a few in my time...

Biggest one I have owned was an Electric Start 11hp Honda on a 200ltr tank - think that was only 23cfm (and the free air delivery rating will be lower than that).

Most petrol engined compressors run at 150psi - but if you really hunt about there are 200psi tyre fitter specials made. These make so much difference - it is unreal.

Electric start is good as well - as most of the time - the compressor will be dumping to atmosphere. Trailing lead with stop/start is just so nicer.

Some years ago i was going to a shooting club meeting with the Chairman in his new to him Transit van. I happened to ask "Do you know anyone flogging a fair sized compressor?", He relied "Yeah theres one in the back!". Previous owner of the van had used it as a base van for banger racing & stuffed a big compressor in the back.
It was an American industrial Equipment Triple cylinder about 16cfm driven by a Kohler Command 6 petrol engine & an unloader valve. Sat on a 150 ltr tank It worked well once it was serviced but that Kohler drinks petrol like its going out of fashion.
You are looking at twice that capacity what about two ingersol rand type 30's? lots of them about, need a big engine to drive them though.

There's several sizes of type 30, two of the very common 2340's would get to there or thereabouts 30cfm.

The bigger sizes which can natively deliver 30cfm are not nearly as cheap... See this 71T2 for example.

For a farm?

Use an engine you already have?

Makes the little 35 wobble with the torque at higher pressures. And I need to find a shorter shaft.
