Abstract: A gear pump includes gears (114, 116) having a gear root diameter (135, 137) and teeth (134, 136) having an addendum and pressure angle. A housing (102) includes a fluid inlet and discharge, bearings (104, 106) configured to position the gear teeth in intermeshing contact across a fluid dam (158). The fluid dam includes a first face (161) arranged at an angle to a split line (152), spaced apart from a center line (150) at the split line a first distance towards the inlet, and extending from the first gear root diameter away from the center line to the first gear root diameter, and a second face (181) arranged approximately perpendicular to the split line (152), spaced apart from the center line at the split line a second distance towards the outlet, and extending between the first gear root diameter and the second gear root diameter.
