After looking at a few spec sheets, I'm convinced their metric policy is Customary design, metric afterthought, or "just enough metric to sell in Europe." Only the HALO series shows dimensions on the spec sheet, all show volume/pressure ratings. A typical rating statement was 180 gpm to 270 gpm at 1000 psi. The metric rating was 40.88 m3/h to 61.32 m3/h at 68.96 bar. I doubt the precision of the Customary spec warrants the precision of the metric spec. All of the HALO drawings give inch dimensions, a few give metric, and metric is in first position when they do. Looking at the dimensions, however, it seems clear the design was Customary, possibly with the exception of some mounting point dimensions.

I didn’t see flow rate anywhere but wonder if they would use std cm3/s, let alone mol/s.

I looked on their web site http://www.pumpengineering.com/ It does have metric units. I wrote to them asking if they designed and manufactured in metric units. If they do, we need to let NPR and other news media know that making it metric will provide jobs here in the US. I'll let you know when I get a reply. Regards, Mike Payne
