"In the past, we had always used gas sprayers. Now we use the QES50 50-gallon pest control power sprayer for our general pest control work, and we love it. It's a real workhorse. We use it six days a week in the blazing Arizona sun. The units are easy for our techs to operate, require little maintenance, and have virtually zero problems. Highly recommended!"

- Arthur Mann, Lil Critters Pest Control, Phoenix AZ

50-Gallon Pest Control Power Sprayer Components

Shurflo 8000 Series 12-Volt Electric Pump & Motor

Why We Use This Pump: We use the Shurflo because it is the most reliable continuous-duty pump on the market. That means you can use it hard, every day, in heat or cold. It will work, and it won't drain your battery. You do not need to leave your truck running when pumping your 50-gallon sprayer tank. This is the ONLY electric pump we will put a money-back guarantee on. Also, every pump eventually needs maintenance. We make this pump easy to get to and easy to remove with spin-on wing-nut fittings. This means maintenance takes minutes, not hours, which reduces downtime and saves you money!


  • Maximum Pressure 100 PSI, 1.6 GPM
  • Pump mounting base kit
  • Automatic demand switch
  • Self-priming
  • Viton valves & Santoprene diaphragms for chemical resistance
  • Can run dry without damage
  • Wingnut fittings – easy access to service pump
  • Electric toggle switch control - mounted on hose reel giving you easy access
  • Waterproof 15-amp fuse & holder

50-Gallon Polyethylene Sprayer Tank - Heavy-Duty

Why We Use This Tank: We plumb our tank from the bottom to reduce the suction problems (and downtime) that eventually occurs with top-plumbed tanks. Plumbing from the top requires the use of a PVC tube, which exposes you to unnecessary risk. The plastic tube can clog, starving your pump. Or it can break or crack, causing your pump to suck air. Plumbing the 50-gallon pest control power sprayer from the bottom eliminates these problems.


  • Secured with steel bands
  • Rugged, impact-resistant, one-piece seamless construction
  • Bottom End plumbed to reduce vapor lock & suction problems
  • 3-Year manufacturer's limited warranty
  • Anti-siphon/backflow prevention device
  • Flexible hose extension to side rail
  • Allows easy tank fill
  • Hose extension reduces stretching & back strain

Cox 1125-4 Hose Reel, Manual Crank

Why We Use This Reel: There are cheaper reels available, but we won't use them. The raised reel design means the 50-gallon sprayer tank unit can sit with the reel facing to the side or to the rear. Most of our clients use the side orientation. Why? Because this allows them to park in the street where an accidental oil leak won't stain a customer's driveway. Cox reels need little maintenance other than occasionally changing the O-rings in the swivel. The swivel is positioned so you can swap out the O-rings in less than 5 minutes.


  • Heavy-Duty steel construction
  • Durable proprietary "CPC" powder coat process
  • Adjustable tension brake to prevent backlash (manual reels only)
  • Rebuildable brass swivel
  • 2-Year manufacturer's limited warranty
  • Heavy-Duty reel lift – virtually indestructible
  • 3/16 steel construction
  • Reduces technician back strain - no bending over
  • Boosts productivity
  • Passenger-side mount for easy access

3/8" Spray Hose – 300 Feet, 600 PSI

Why We Use This Hose: We use much higher quality hose than the pump requires for 50-gallon pest control power sprayers because we want it to last and we don't want you to have to worry about your spray hose.


  • Heavy-duty, chemical resistant
  • Quick disconnect – for easy tool interchange
  • Ball valve at hose end for emergency shut off – improves safety
  • Durable high-quality stainless steel band clamp at hose
  • Reduces spills
  • Reduces technician injuries

Green Garde 38505 Spray Gun

Why We Use This Spray Gun: We like the Green Garde gun for the 50-gallon sprayer tank because it is more durable and takes abuse better than a lot of other spray guns. It is easily rebuildable with an o-ring kit. We do have other spray guns available if you prefer (additional charge may apply)


  • Heavy-duty construction for reliable service
  • Stainless steel valve stem and tip
  • Aluminum body – durable & light weight
  • Chemical-resistant Viton seals
  • Adjustable stream
  • Rebuildable
  • Quick disconnect allows you to easily remove gun to use a different gun or tool; as well as for security, storage, and maintenance

Filter/Line Strainer

Why We Use This Strainer: Checking the filter frequently is the easiest and most important thing you can do to reduce sprayer problems & extend equipment life. Unlike so many other company's 50-gallon sprayer tanks, our filter is easily accessible, even when the tank is full.


  • Chemical-resistant Viton gasket
  • Stainless-steel screen
  • Easily accessible by technician
  • Brass gate valve allows checking in the field without emptying tank

Heavy Duty Quality-Designed Steel Frame

Why We Use This Frame: Many companies design sprayers to be cheap and easy to ship. Our 50-gallon pest control power sprayers are designed for ease of use, safety and easy maintenance. It is not worth saving a few dollars on the purchase price if the sprayer always needs service or if service takes forever because the components are difficult to access.

Why The Raised Design Is Important: Most frames sit flat on the truck. Chemicals build up. Dirt collects. Our raised 50-gallon sprayer tank design allows you to keep this area clean and safe so you can project a professional image. You work hard to win & retain customers. Why take the chance of handing over a customer to a competitor because of filthy, smelly truck?


- 3/16" thick steel – virtually indestructible

- Joints are welded top and bottom for extra strength

- All rig components easily accessible for maintenance

- Painted for durable finish

- Raised design allows for easy cleanout under frame


"Frontline has standardized our equipment, our choice was Quality Equipment, and we have nearly 30 QES50 50-gallon sprayer tanks installed. The rig design minimizes the real estate requirement in your truck. Rugged, durable design and easy serviceability have dramatically reduced equipment repairs and downtime. I would highly recommend their equipment to anyone requiring dependable products at a reasonable price."

- John Barnett, Associate Certified Entomologist, Frontline Pest Professionals

"We have purchased 30 of the Quality Equipment QES50 spray rigs. Our techs find them easy to use. As a company owner, I appreciate their reliability, their durability, and the relative lack of maintenance required to keep them running. We recommend this 50-gallon sprayer tank and this company to anyone doing pest or weed control."

-Dan Stevens, President - Evergreen Pest Solutions

About Our Pricing Philosophy

Our pricing is not the lowest on the market. So if you're someone who shops by price only, we probably aren't for you. But if you're a savvy buyer - someone who understands that cost, NOT price alone, is the true sniff test for overall value - this should interest you… Our products are made with brass fittings & valves. Brass costs more but provides strength, reliability, and durability and lowers the risk of costly chemical leaks & spills! We stock ALL the repair parts and kits you are ever likely to need for this sprayer. Unnecessarily waiting for parts is the #1 silent profit-killer that impacts many operators. Our approach, too, is simple: Build a quality product and keep maintenance and repairs to a minimum. That way, we help you maximize your operating time and productivity and - most importantly - your profits!

And we back it up with our 90-Day Money Back Guarantee - the only one in the industry.
