  • Pump propeller guard
    Patent number: 11873843
    Abstract: An improved guard for a pump propeller is described herein. The guard includes a hub that in use surrounds a drive shaft of a drive motor unit that drives the propeller. The vanes define a propeller receiving area in which the propeller is received allowing the propeller to rotate relative to the vanes, while portions of the vanes radially surround the propeller. The guard is fixed in position about the propeller to protect the propeller from debris and to prevent human contact with the rotating propeller. The guard is designed to shed weeds and other debris, and prevent weeds and other debris from becoming entangled on the guard and with the propeller.
