The ornamental design of a pump and tankassembly for a hand-operated sprayer, as shown and described.
FIG. 1 is a perspective view from the front of a pump and tank assembly for a hand-operated sprayer showing the pump handle withdrawn upwardly;
FIG. 2 is a perspective view from the back showing my design, but with the pump handle depressed so that the handle is flush with the tank, wherein the hose and nozzle wand is not part of my design in both FIGS. 1 and 2; and,
FIG. 3 is a perspective view similar to FIG. 2 looking from the left showing my design.
The broken line showing of the hose and nozzle wand is included for the purpose of illustrating and forms no part of the claimed design.
