  • Vacuum pump for agricultural seeding equipment
    Patent number: 7140311
    Abstract: A vacuum pump for a seed planter includes a housing, an impeller rotated within the housing, and a motor or other drive. The housing has a central inlet and a circumferentially arranged outlet passage. The impeller vanes define air paths that are open to the outlet passage. The impeller has a central aperture for coupling to the output shaft of the drive and an impeller center cap screwed into the central aperture. The impeller has a curved conical center hub that surrounds the central aperture. The center hub and the center cap are configured to smoothly direct air flow to the passages between the vanes to reduce or eliminate a stagnant air region in a center of the impeller. The center cap can also be used as a tool to remove the impeller from the output shaft.
