Any idea if cavitation can occur in a positive displacement vane pump, and if so how, presumaly not the same way as a centrifugal as the impeller is curved in centriugal pump unlike a PD vane pump?

Cavitation will occur on any liquid if the pressure is lowered enough and/or temp is high enough and will affect a vane pump. On all the hydraulic pumps I've seen ,there is a maximum negative pressure that is allowable(this is on the suction side) -regardless of what type pump and what the pumping medium a pump will last longer,run cooler and quieter and be more efficient if it is set up with a flooded suction. Most common causes I've seen for cavitation on the suction side of a hydraulic pump is clogged suction strainer,undersized suction line,cold oil,blockage in suction line from some foreign object. Hope this helps, Maytag
