The exclusive internal No Leak Pump keeps your back and clothing dry. The paddles keep liquids, powders, and water-soluble solutions mixed, in solution, and ready to spray. Also the pump features Viton seals that can be easily changed within minutes without tools (up to 7x faster than the leading competitor). The premium shut-off offers a comfort grip, lockable trigger to prevent hand fatigue, and a removable in-line filter to reduce clogging. The Field King Max 190348 Backpack Sprayer is capable of spraying up to 150 PSI - perfect for those hard-to-reach areas. The included pressure regulator maintains a low, continuous 25 PSI (great for spraying herbicides). The foldable pump handle reverses for left- or right-handed use, and the tank has a built-in carry handle with wand storage. Our deluxe harness features a full back pad, wide support waist belt and chest cinch strap ensuring comfort while you work. Multiple nozzles are included for ultimate versatility: brass adjustable nozzle (enables stream to cone patterns), wide flat fan nozzle (red, 0.25 GPM, angled at 70), narrow flat fan nozzle (yellow, 0.15 GPM, angled at 30), and foaming nozzle.

Here is a list of the Field King MAX 190348 upgrades: 1) 21" stainless steel wand with chemical resistant poly lining. 2) Deluxe padded harness with back pad and lumbar support, adjustable shoulder straps, waist belt and chest cinch strap. This backpack harness ensures all-day comfort while you work. 3) Fold away pump handle for easy storage. Both backpack sprayers are equipped with the internal, No Leak Pump which prevents liquids from leaking down your back. The internal pressure chamber can reach up to 150 PSI allowing a straight stream to reach 30 feet (dependent on the chemical being sprayed). Also they both have Viton seals for resistance to harsh chemicals and dual filtration to prevent clogging.

Thank you for your interest in our products. **Q: does this have a built it agitator and can wettable powders be used in it** A: No agitation. It’s a manual backpack. **Q: So i have a pest control company and i was looking to add a back pack - any pco out there using this or i am open to other suggestions??** A: HI, This unit is ideal for use with cleaning solutions, disinfectants, stains, sealants, fertilizers, herbicides, and fungicides to help beautify your outdoor areas. I don't see anything saying that it can't be used for pest control. Thanks! **Q: does this version also come with the 25psi regulator?** A: It has a pressure regulator, but I think of it more as a no drip regulator that prevents the the spray that remains in the wand from dripping if the pressure gets below 25 psi. It also ensures a clean spray pattern as most nozzles don't do a good job of dispersing the spray below that pressure. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality product. *by P***Y on Reviewed in the United Kingdom on 25 June 2021* Only just assembled it however it seems to be good quality and comfortable to use. It comes with a decent harness which it's competitor (Solo) does not and It has four nozzles plus a pressure reducer. I particularly like when you pump it agitates the fluid. Ordered this from Amazon U.S. and did not have to pay import duty which was a surprise.Update. Just used it for the first time. Only half filled it to reduce the weight, it is better to put it on from a table etc. so as to avoid lifting. Once it is on you back it does not feel too heavy due to the supplied harness. Works very well but does need regular pumping, however once you get used to it it is not a problem and much more convenient than my old small Hoselock. Might splash out on an electric model next time ## Frequently Bought Together - Field King Max 190348 Backpack Sprayer for Professionals Applying Herbicides - Southern Ag Surfactant for Herbicides Non-Ionic, 16oz, 1 Pint - Liquid Harvest Lazer Blue Concentrated Spray Pattern Indicator 8 Ounces Perfect Weed Dye, Herbicide Fertilizer Marking Turf Mark and Marker --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/261311115-d-b-smith-190348-max-professional-s2-backpack-sprayer-4gallon](https://www.desertcart.ec/products/261311115-d-b-smith-190348-max-professional-s2-backpack-sprayer-4gallon) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-04-24*
