Reply to "Oils, cavitation and viscosity"

A interesting animation of cavitation inside a gerotor pump.

Gerotors usually require the depth of the inlet ports to be at least the same as the width of the gerotor.

The ports in the 351c pump are less than that.

I think the opinion given in Sticky 3 about the 351c pump needing two inlets is correct.

The wide 351c gerotor needs to be fed oil from both sides instead of just one.

This animation shows a deep inlet port below the gerotor and a narrow "shadow port" above. Note the constant cavitation in the shadow port and cavitation in almost 3/4 of the gerotor.
