I am trying to find a tech bulliten, or any other possible information on the SUNDSTRAND model 36-2119 heavy duty, hydrostatic pump. It has 12VDC EDC servo control with pressure limiters and manual override. Charge pump pressure 230-250 PSI. Charge pump has spin-on filter.
The specification known are:
6.0 cu. in. per rev. disp.
3,500 PSI cont.
6,000 PSI int.
2,880 RPM max
50 GPM at 2,000 RPM
1.30 cu. in. per rev. charge pump disp.
4 bolt, SAE C mount
CCW input rotation
Ports: A/B-1" 6000 PSI 4 bolt flange
Case drain-SAE 12
Charge pump inlet-SAE 12
1-3/4" dia. x 2-1/8" long 13 tooth splined input shaft
Overall size 16" x 14" x 12"
Shpg 225 lb
I am most concerned with the controls of this pump. The Sunstrand pump is electronically controlled, proportional over hydraulic. We need documentation so we can interface with it. We may be able to bypass the EDC and drive it hydraulically, but some additional data is needed.
We have searched and searched, and cannot find any data on this pump. I know it is an older pump and is definately been out of production for a while. I called a couple repair places, and they can't even find repair parts.
If anyone has any experience with this pump, or has any data stuffed in their file cabinets, or anything, we would greatly appreciate it.
