Pump rotation?
[Return to Topics]

I have a hydraulic pump - nice one, looks about right, have no way of finding out exactly what it is, the GPM or anything. It's pretty hood sized (about a double handful), 2 mounting holes, it's painted yellow and has maybe a 5/8" shaft. Well if it pumps oil, that's all i need to know for now - brand doesn't matter. So my question is - how would i determine direction of rotation before i mount the darn thing.

DC if its not marked in or out, and one port is bigger that the suction side. The smaller is the pressure side. If bother ports are the same and it has no arrows for rotation its bidirectional. If its marked and a gear pump and its the wrong direction you can leave the flange in the same postion and flip the body over. just put the internal check valves on the opposite sides. Sorry if it sounds like Greek, its hard to explain but simple to do.

DC, if your ports are marked in and out, pour some oil in the "in" port and rotate it by hand, if it comes out the "out" port ya got it right. If it tries to come out the in port, go t'udder way.
