Dry Sump Pump

Dry Sump Pump

Dry Sump Pump

(OP)
Looking at an old 1960's formula 1 dry sump pump the other day and wondered when the transition was made to the 'rotor' style pumps.
Also wondered if the gear pumps were able to perform at a similar level as far as oil pressure/volume/scavenging of crankcase.

Can someone educate me on the differences/values of each.

RE: Dry Sump Pump

Gerotor pumps have higher vacuum, and also allow for higher rpm, they don't cavitate as early as gear pumps. As for volume/pressure vs size, I think the Gerotor is slightly more compact as well. But not 100% sure.

RE: Dry Sump Pump

(OP)
Thank you that is helpful information. A local manufacturer only offered 'they are more effecient', which was not very informative.

RE: Dry Sump Pump

i believe the reason for the high rpm difficulties would be that the gear type is positive displacement.
