Details

The Comet APS71 is a high pressure, three diaphragm pump that is internally manifolded and features anodized aluminum heads for less leakage. The pump is great for high pressure applications, including lawn care, weed control, pest control, agricultural spraying, tree spraying, and hydrostatic testing.

This pump is perfectly capable of handling the pumping of a wide variety of agricultural chemicals, such as herbicides, pesticides, liquid fertilizers, abrasives, de-icing materials, and other hard-to-handle liquids.

APS71-GR5: Three diaphragm pump with gear reduction for gas engines with 3/4" (19 mm) shafts. Comes with pressure regulator with manual dump lever.

APS71-GR8: Three diaphragm pump with gear reduction for gas engines with 1" (25 mm) shafts. Comes with pressure regulator with manual dump lever.
