The diaphragm design is primarily utilized for wettable powder fungicides. Compared to piston pumps, the diaphragm design is more forgiving due to the abrasive nature of powders. The large pump enables quick pressurization with fewer pumping motions. An internal 4-position spray valve provides expert pressure control, ranging from 15 P.S.I. to 60 P.S.I. Padded carrying straps ensure fatigue-free operation. The easy-to-use spray handle features a continuous spray function. The package includes a multi-use nozzle tip selection. The pump handle can be positioned for use with the right or left hand.

The 4-gallon translucent tank boasts a 4-inch wide mouth opening, facilitating easy filling and cleaning. The diaphragm pump offers compatibility with common fertilizers, weed killers, and pesticides in both liquid and wettable powder forms. A 3-stage filtration system with an in-tank removable and cleanable filter is incorporated.

The cushion grip poly shut-off comes equipped with three nozzles, catering to a variety of applications. Padded shoulder straps allow for comfortable use even when the backpack is fully loaded, enabling extended periods of operation.

In summary, this diaphragm-based sprayer is designed to handle wettable powder fungicides effectively. Its forgiving diaphragm design, large pump, and internal pressure control valve make it a versatile choice. The ergonomic features, such as padded straps and an adjustable pump handle, contribute to user comfort and fatigue-free use. The 4-gallon tank, 3-stage filtration, and wide-mouth opening provide ample capacity and ease of maintenance. The included nozzle tips and compatibility with various chemicals make this sprayer a multi-purpose tool for agricultural and gardening tasks.
