Hyd Pump - What did I just buy?

[ihbuilder]

I can get a shaft seal for them , but the specs are for low speed not to mention $$$ . when you dish out leave the area at the shaft in so it goes against the pump housing at the shaft . I was going to do what you did just have the motor stacked on top of the pump using a timing belt and gears/pulley much like verio's setup . I just have my rotary setup for hubs and don't want to take the jig off till the cnc mill is running . I def. got a bad sevo amp now just to get 1 or 2 , 1 for the 4th axis
