You are looking at at a used John S. Barnes Small Hydraulic Pump for equipment. The model number is #3194, P109932. I do not know of the condition of this pump, I did take the caps out so you could see that there is no rust on the interior. I have no way to test this item, I bought this used and have stored it for many years.
This may be used on log splitters, I'm not sure. Be sure to ask any questions you have before purchasing. This item is in the category "Business & Industrial\Hydraulics, Pneumatics, Pumps & Plumbing\Pumps & Pump Accessories\Hydraulic Pumps". The seller is "rnl03" and is located in this country: US. This item can be shipped to United States.
