There's nothing wrong with Quincy oil pumps. In fact they have fewer parts than a gear type pump, so they may be a better design. Quincy's don't need needle bearings in the wrist pins, they have full pressure lube to the pins. No need to bash Quincy QR 25 series. Only the box store QP series are the ones to stay away from.Saylor-Beall made in USA for 107 years and counting. Union shop.
Comparable tonnage per horsepower and RPMs to Quincy's QR-25 lineup. They are big, heavy low speed pumps. They've retained some of the more expensive old-school design features that Quincy phased out beginning in the 50's like centrifugal unloaders and gear-type oil pumps. The wrist pins have needle bearings too, whereas all the Quincies have plain bearings there AFAIK. They both have the same disc-type valves instead of cheaper reed valves (which some of the Ingersols are notorious for if I'm remembering correctly.)
Of course there is the matter of the price tag... A bare 10 horse PL-707 pump alone will put you out four and a half grand. Then again a comparable QR-25 will do about the same.
Buy once, cry once / get-what-you-pay-for and all that. Upfront cost vs false economy resulting from downtime of a cheaper unit in a production environment, yada yada.
Now you have a chance to do it right!The good news about the POS air compressor that Ingersoll-Rand won't even return a call after leaving 5 voice mails and a email message. MSC has issued me a return authorization for a full refund, I will be taking it to MSC's facility tomorrow. Evidently MSC could never get IR to return their calls also. IR has to be one of the stupidest companies putting a big label on the tank (PROUDLY ASSEMBLED IN THE USA), they don't advertise the fact that it is assembled with shitty garbage parts.
