| It is well known that gear pump output, under controlled conditions, correlates linearly with pump speed, so pump output can be extrapolated to higher operation speeds with good confidence. \\ | It is well known that gear pump output, under controlled conditions, correlates linearly with pump speed, so pump output can be extrapolated to higher operation speeds with good confidence. \\ | ||
| - | The data table and plot below show select results from pump tests. The -72 gear pump tested here had impressive output, since the pump volume at 2500 rpm was greater than 1.3 qt/min. Thus, there is certainly a generous amount of oil going through any KH/XL engine which would have similar, if not identical, feed gears. To add a bit of historical context here, the subsequent XL gerotor pumps employed from 1977 forward, pump ~ 50% higher volume than the -72 gear pump (see HippySmack's data table in Appendix for comparison). | + | The data table and plot below show select results from pump tests.

To add a bit of historical context here, the subsequent XL gerotor pumps employed from 1977-1985 pump slightly less and 1986-up versions pump ~ 50% higher volumes than the -72 gear pump (see HippySmack's data table in Appendix for comparison). |
