Notes: MAX RPM is shown at 0 in.hg. and with an appropriately sized inlet hose MAX motor back pressure is not to exceed 150 PSI (10 BAR) MAX inlet vacuum is not to exceed 5in.hg. (0.17 BAR) Weights shown are for single, direct mount pumps Porting shown is standard pump porting, other porting configurations are available Motor applications will require a case drain to be plumbed directly back to the reservoir due to excessive return line pressures or surges
