GEAR PUMP Rapid wear in a gear pump construction due to shaft deflection during pump operation and of the sort including a housing having an interior wall defining a pumping chamber, opposed inlet and outlet ports meshed gears within the chamber, a pair of shafts mounting the gears and bushings journalling the shafts is avoided by providing at least some of the bushings near their ends remote from the gears and on their sides remote from the outlet with radially outwardly opening slots extending generally transverse to the shafts.
