Today we are featuring steps on how to get started with this 2-wheel sprayer. Follow the easy steps outlined below and don't forget to watch the instructional video right at the end of this post!

Starting Your Sprayer for the First Time

1. Ensure all unnecessary personnel are clear of the area.
2. For initial testing, it is recommended to start with clean water instead of chemicals to confirm the system and plumbing components are leak free.
3. Ensure there is fluid in the tank and supply line.
4. Check line strainer for debris or clogs and remove any if found.
5. Check all plumbing connections to ensure tightness.
6. Ensure all valves and regulators are set to the desired setting and working properly.
7. Ensure all hoses are positioned properly and undamaged.

Follow these steps to start the engine

1. First, remove the boot clamps from either boom and extend the booms.
2. For a cold start, pull the choke out to FULL.
3. Set the throttle to slightly above OFF.
4. Pull start the engine.
5. Release the choke by pushing it in fully.
6. Raise the throttle to FULL.
7. The knob at the top of the regulator handles the pressure; adjust the pressure to roughly 200 psi.
8. Turn the agitator ON; you’ll notice a slight drop in pressure.
9. Adjust the spray gun to the correct setting and you are ready to spray.
10. The spray boom has seven spray settings: left, right, center, left/right, left/right/center, left/center, right/center.

Shutting Down Your Sprayer

1. Set the pressure regulator to OFF.
2. Slowly lower the throttle to OFF.
3. Raise the booms and replace the boom clamps.
4. If the pump will not be used for several hours, flush your system to prolong the life of the unit.

Guest Post: Hypro Boom Components

Mark Techler,  Factory Representative - Hypro & SHURflo Ag and Industrial Pumps and Accessories

Some of the top sprayer manufacturers, plus leading chemical manufacturers like BASF and Syngenta, are partnering with Hypro in developing spray boom components to meet the demands of today’s precision spraying. 

Nozzle Bodies
There is a certain amount of pressure lost when liquid flows through any spray component. This is "pressure drop". Hypro ProFlo nozzle bodies have the lowest pressure drop at any given flow in the industry, for instance 2.6 gpm with 5 psi pressure drop. This adds to system efficiency and supports faster field speeds. Other ProFlo features:

  • Single, 3, and 5 way nozzle bodies for wet and dry booms

  • Diaphragm check valves in EPDM or Viton

  • Reliable turret index provides positive shutoff between positions

  • Full line of nozzle body accessories (caps, barbs, adapters, clamps, etc.)

Express End Caps and Fittings
Air gets trapped in booms and causes the nozzle to actuate non-uniformly, resulting in under/over spraying of targets. Hypro’s unique Express End Caps and Fittings, designed for 1-inch stainless tubes, permit all the air to leave the boom, allowing uniform spraying. Clean-out ports eliminate “dead ends” on booms that accumulate unwanted chemicals. 

Spray Tips
Hypro has a full line of agricultural spray tips including fan, cone, flooding, plastic, ceramic, and a broad range of flow rates. Only Hypro offers:

  • Ultra Lo-Drift tips. The ULD, with an air induction fan spray, provides the best combination of drift control and coverage in the industry.
  • GuardianAir Twin. The GAT, with forward and rear air induction fans, is the best choice for high coverage targets and complex canopies.
  • The industry’s best spray tip selection tool. To use the SprayIT calculator, enter your spray parameters and Hypro will show you the available tip options.
  • The industry’s best mobile app for spray tips. From your mobile device enter your spray parameters and the chemical name and Hypro will show you the available tip options. Find it here on iTunes and here on Google PlayYou can also access the recommended spray quality for many popular ag chemicals andmatch the droplet size to Hypro spray tips.

Choose the Right Roller Pump

Posted by Sprayer Depot on Wed, Nov 12, 2014

Hypro roller pumpChoosing the right roller pump for your sprayer and application needs can be tricky. After all, the pump is the heart of the sprayer and roller pumps are the top all-around choice for agriculture and industrial spraying. This includes turf spraying of herbicides and pesticides, liquid fertilizers and many other liquids. These spray pumps have a low initial cost and are pretty versatile too. Still, there’s no one solution that meets everyone’s needs making the search for the best solution at times mystifying.

Before we get into the nitty gritty, it’s important to note the basics. A roller pump has 4 to 8 rollers depending on the model, that revolve inside the pump housing to force the spray solution out to the nozzle. These pumps operate at PTO speeds of 540 and 1000 rpm – a definite point to note for choosing the right pump. Roller pumps have a pressure range up to 300 psi and flow rates up to 74 gpm. These products are self-priming and easily adapt to PTO or gas engine drives. These pumps require no check valves while providing positive displacement characteristics. Got it? Good. Now let’s get into choosing the right roller pump.

Consider this real-life scenario that one of our customers shared with us:

“I bought a used 55 gallon tank sprayer with wand and boom for spraying weeds and fire control. It had a 4 roller pump on it that quit/froze a year and a half ago. I replaced with another 4 roller pump and this spring it froze again. The sprayer has a 3hp Briggs motor with a 5/8'' shaft. I would like to know if I can use a larger pump and/or what you would suggest.”

Know the answer? If not, take a look at the steps below for easy identification of the roller pump that will meet your needs. Or skip ahead and check out the solution for this particular scenario.

3 Steps for Pump Selection:

1.) Determine your highest spraying pressure (psi).

For spray guns, 40 psi is often typical at the nozzle, but to properly select a pump that can deliver the right spray pressure, you should calculate it yourself. Keep in mind that pressure losses are normal and should be factored into the equation. It’s recommended that you add 120 psi for system pressure losses.

Desired Pressure at Nozzle (psi)
+ Hose Pressure Loss (psi)
Total Pump Pressure Needed (psi)

2.) Calculate the total pump flow (gpm) using the formula below.

Now you’ll need to know the boom flow and agitation for that calculation. You can determine your boom flow (gpm) by multiplying the gpm per nozzle by the number of nozzles. The flow required for agitation is a little easier as that is determined by tank size. For a 500-gallon tank you’re looking at 25gpm, 750-gallon tank will be 37 gpm, 1,000-gallon tank at 50 gpm and 1,500-gallon tank at 75 gpm.  

Boom Flow (gpm)  
+ Agitation (gpm)
Total Pump Flow (gpm)

3.) Choose the pump based on the manufacturer’s catalog performance charts.

Sounds simple, but in addition to the numbers you just crunched you’ll also want to keep chemical compatibility in mind. Specific seal, roller and casting materials can be selected for compatibility with certain herbicides, pesticides, fungicides and fertilizers. The three housing material options – Cast Iron such as the Delavan line, Ni-Resist or Silver (for these purposes we’ll be referring to Hypro’s Silver Series XL roller pumps) – are particularly important for total pump life. Studies have shown, especially with weed control chemicals such as Roundup that the Silver Series XL line is more durable and affords a 10x longer pump life.

Now back to our example. This customer had a standard gas engine without gear reduction. In that case, the best solution was to replace the pump with another 4 roller pump (product 4101C) and keep an eye on maintenance for better long-term wear. Another solution would have been to use a different model, but that would have resulted in purchasing a gear reduced engine. In the long run, this customer was better off just replacing the pump with the same model.
