My CH pump finally gave up, and I am looking for a new pump. I would like to know what mfg. has the pump with the most cfm @90lbs. The old CH had 3" bore w/ 2" stroke. It threw a piston out the side of the case on cold start up. The compressor unit is a 30 gallon horizontal tank platform and sits in an almost inaccessible area and cannot be relocated. My constraints are: has to be single stage, twin inline, 125-155lbs. w/p , near 100% duty cycle. I have 3, 5, and 7.5hp -3450rpm motors that can be mounted on frame to run pump. Ideally would produce over 13cfm. Thank you for your ideas.

At times there are 3 Ingersoll-Rand air motors running at once. The old CH put out 11.5 scfm @90lbs. As stated I'm looking for at least 13scfm or greater to keep up. I have an additional 30gallon tank inline as a buffer. What I'm looking for is the mfg. and model # of a pump with more capacity so it can take a break at times while running under these conditions. Thank you.
