Subject: Info for old Commercial Intertech Hydraulic Pump



ND		We are trying to mount a pump on our 936 Versatile to run the fan motor on our air cart. We pulled it off of a 850 Versatile that was using it for the same thing. I was wondering if any one new where to find info on flow and pressure at a rated rpm.

Commercial Intertech by Mid-American Power Drives
Pt. No - 326-9110-169

I've been searching the internet for a couple hours with no luck so if any one could help that would be amazing.

ND		I seen that website but couldn't find anything on my part number. Might just have to call them or someone else in the morning to see if they have any info on older pump numbers.

Winkler, Manitoba Canada		I've had the same problem. It seems that the part number often doesn't match with the catalogue number. I thought the identification info on that page might allow you to figure out what you have. Phoning might be your only option though. How do you drive the pump on the cummins? Belt drive from the crank?

ND		yeah we are going off the crank. It has an electric clutch that looks identical to an A/C electric clutch and we will have to set up the rest of the system on our own, but it's worth a try because it would save alot of money compared to buying the Atom Jet setup.

NW Washington		Northern Tool and the Surplus Center both sell belt driven hydraulic pumps with electric clutches, but they don't say who makes them. The do have the pump displacement listed. See if these look familiar. http://www.surpluscenter.com/sort.asp?UID=2009031001042944&catname=...

Baum Hydraulics carries Commercial Intertech pumps. I see a few part numbers that begin with 391-, but not your number. You could call them at 800-228-9222 and ask.

Mid-Missouri		Slightly off topic but...We have a 936 and 895. If the time came were our hyd.pump went out or we needed more flow, why can't the original pump be replaced with a larger one. Or, why can't you piggyback a pump inbetween the original? I know some drive one off the crank which also sounds pretty simple. Thanks.

Winkler, Manitoba Canada		Pump drive on the 855 Cummins in those tractors is pretty limited. Larger pump likely means broken engine lube pump drive shaft.

Germantown, Ohio		I will look that number up and get you some specs. That should be a good C/I #. I'll let you know later today.

Germantown, Ohio		It is a C/I 326-9110-169 = P315A189UNAB15-56 CLUTCH PUMP Should have 1.5" gear set which would be 1.7 ci/rev rated to max 3250 psi. Electric clutch and belt will probably never get to that pressure, but the pump will do it.

To get flow rate @ a given speed:

ci/rev x input rpm/231= gpm

SO: 1.7 ci/rev x 1200 rpm/231= 8.83 gpm

I have a similar question. I have a CI pump with a part number 321-9111-04. Do you know what the displacement would be for this pump?
