Not to bust a bubble, but I'm afraid that pump is a low pressure water/spray pump. Notice how it says "flush with oil after use", and it only has one shaft. Vane pumps only have one shaft, but it's not a vane pump. Looks to be a "roller pump".
Thanks, Daniel! I started a thread on the pump trying to figure this all out! But I do have 2 Char-Lynn hyd. motors and valve!
