Anchor to Specifications and Description


The HD Hudson Multipurpose 4-Gallon Multipurpose Bak Pak Sprayer lets you get your back into your garden-spraying needs with a convenient design that doesn’t require you to lug a sprayer by hand or pull one on wheels. This backpack sprayer is especially convenient if you have some distance to cover with your spraying or if you need to walk along rows of crops or garden produce. You can just strap it on and away you go. The sprayer comes with a diaphragm pump. Diaphragm pumps tend to be more durable than piston pumps because they keep the pump’s parts separate from the liquids you’re spraying. This diaphragm pump can reach up to 70 psi and, unlike piston-pump sprayers, can be used with wettable powders, abrasive or bleach solutions. The pump also has a tough solid-steel handle for long-lasting service. To get this sprayer going, you pressurize the tank by pumping it up to 25 times, then continue pumping every 5 seconds as you go to maintain the most reliable, steady pressure. The backpack sprayer comes with straps that provide a comfortable fit for continuous use in the garden. With the see-through 4-gallon tank, you can check liquid levels at a quick glance. A 47-inch spray hose and 20-inch brass wand with adjustable-pattern nozzle gives you the flexibility to provide chemical treatments and water just where you need them. And it has a locking shut-off valve with built-in filter. You can use this backpack sprayer to water plants, apply insecticides or herbicides, apply sealant to concrete or wood, and a variety of other outdoor water chores. Make sure you carefully and completely clean it out after every use. This versatile sprayer will become one of your favorite tools.
