The voltage is a possibility for sure, but your oil pump manufacturer is OILDYNE. So they make also different combinations in term of flow and voltage 12VDC/24VDC/36VDC:
,Four standard pump sizes which produce flows of .0098, .0187, .0246, and .0321 cubic inches per revolution
Check the link hereunder , and compare to the reference number you have on yours to see the internal technical differences, if any.
But when you write half the speed , it's difficult to understand if you are telling the rpm of your motor pump, or the result of the oïl jack displacement speed...
because a different voltage with a different pump flow , should make a big difference.
