The ornamental design for a waterpump, as shown and described.
FIG. 1 is a perspective top and front view of my water pump;
FIG. 2 is a left side view of my water pump;
FIG. 3 is a right side view of my water pump;
FIG. 4 is a front view of my water pump;
FIG. 5 is a rear view of my water pump;
FIG. 6 is a top view of my water pump; and,
FIG. 7 is a bottom view of my water pump.
The top views FIGS. 1 and 6 show elongate recesses with multiple openings through which parts arranged in the interior of my water pump can be seen; the parts in the interior are disclaimed. FIG. 3 shows parts of the interior viewed through the pipe socket; the parts in the interior are disclaimed. Due to the viewing angle, the side views FIGS. 2 and 3 show the contour lines of the ribs arranged between the recesses at the top side merging into each other so as to be no longer discernable in the drawings; likewise, the contours of the ribs between the elongate recesses extending vertically on the front and rear sides also merge in the side view of FIG. 2 and are no longer discernable in the drawing.
The broken lines in FIGS. 2, 3, 6, and 7 are included for the purpose of illustrating portions of the water pump that form no part of the claimed design.
