Pump Curves for IR

Pump Curves for IR

Pump Curves for IR

I need pump curves for Ingersoll Rand APL series pump.  In particular 12 and 14.  My real question is who now represents the APL pump line.  It appears Ingersoll Rand no longer markets the APL series.

Thank you,


RE: Pump Curves for IR

DDS1, I/R pumps was picked up by the Flowserve Pump Division, along with a bunch of other pump manufacturers. Flowserve has since combined the lines, and culled duplicates from their new product line and outsourced a number of them. Check the following link:


Good luck.

RE: Pump Curves for IR


Thanks for your reply.  We had contacted our local rep. for flowserve and he is looking for the curves.  I should have elaborated a bit.  The pump is a number of years (decades)old.  We had hoped that like many other dated lines someone had aquired the casting rights and were still casting the old IR APL series pumps and selling them under some other brand.  They quite possibly would have then the archives containing the older curves for this series.  We have provided several pump vendors the pertinent information and they are persuing it. Thanks again Saxon.


RE: Pump Curves for IR

If you have these pumps and can measure them, including the impeller, then it should be possible to dream up an approximate performance curve. Unless it is a real oddball.



RE: Pump Curves for IR


One of the pump vendors has produced the sought after  curves.  

smckennz, The pumps are in a 24hr service and several states away.  We have in the past taken measurements and plotted our own pump curves but only after exhausting other resourses, like this one.  Thanks for your reply.
