Posted by Sprayer Depot on Fri, Jun 30, 2017

We receive many calls and emails from customers requesting help troubleshooting the Hypro D30 diaphragm pump.  In this post, we've updated some information previously published on this topic to highlight some easy-to-identify solutions.

One of the top-selling pumps at Sprayer Depot, the Hypro D30 offers low cost maintenance and almost wear-free operation which helps make it the ideal choice for a wide variety of spraying jobs. Recommended for spraying herbicides, pesticides, liquid fertilizers, and many other hard-to-handle fluids, the Hypro D30 is not only one of our top-selling pumps, but also the preferred choice for several of our small to medium-sized Kings Sprayers® models.

Properly maintaining your pump will not only increase your application efficiency but also add years of life to your equipment. Follow these easy tips to service your diaphragm pump:

1. After usage, flush the pump with clean water.

2. Hypro recommends changing oil after 40 hours of break-in operation and every three months or 500 hours, whichever comes first. Use Hypro pump oil , which is a specially formulated, high-grade, non- detergent, SAE 30 weight oil.

3. For freezing conditions, flush the pump with a 50/50 mixture of water and antifreeze.

4. Change diaphragms every 500 hours or three months, whichever comes first.

How Planning For Parts Can Save You Time & Money

Posted by Sprayer Depot on Wed, Jun 21, 2017

It's officially summer, and that means it's the time of year many of us are working at full capacity to maximize the business opportunities of the season.  Jd9C-Repair-Kit.jpgA little planning can go a long way, though. Making sure that equipment is running properly means making sure your equipment is in full operational condition and having spare parts on hand, just in case of a break-down and things don't go according to plan. 

Top 4 Sprayer Parts To Keep In Stock

Keep spare parts on hand for items that commonly wear out. Consider this part of your spray equipment maintenance plan. You will be glad when all it takes is a simple repair to keep your spray equipment up and running. Here are some popular items that top our list of of recommended parts to keep on hand:

  1. Sprayer tips and nozzles
  2. Strainers
  3. Hypro D30 Diaphragm pump repair kit
  4. Spray guns

Since damaged spray tips are often overlooked, and can cost both time and money if not replaced in a time, it's a no-brainer to keep somne extra tips on hand. The same goes for strainers; they are inexpensive and easy to replace.  While it's always a good idea to keep a spray gun repair kit on hand such as the this one for the JD9®-C spray gun which includes a Teflon valve seat, having an extra spray gun at-the-ready ensures you've got a back-up plan. This short instructional video is a great refresher.

The Top Questions From Our Blog: Asked and Answered

Posted by Sprayer Depot on Tue, Apr 25, 2017

These days, information is literally at our fingertips; a quick Google search can find an answer to a question that would have taken hours or even days to research just a few decades ago. At Sprayer Depot, we're on the leading questions-answers-723x334.jpgedge of technology. This is evident in everything from our state-of-the-art inventory management system, to our communication on social channels like Facebook, Twitter and Instagram, and our commitment to digital media.

We realize that time is money for our customers. The LESS time they have to spend researching how to do a quick equipment repair on the fly, or a reputable parts vendor,  the MORE time they have to service customers and grow their business. So we quickly respond to all questions on our blog, or social channels and post the answers so they can be referenced by anyone.

In this post we'll feature a few questions that have recently been posted to our blog comment box. 

Q:  "My Shurflo ATV sprayer pump (pump model #8000-543-936pulsates. What's wrong?" - Tom R.    

A: To prevent pulsing try holding down the trigger on the spray wand and adjust the small Allen    screw in the front center of the pump head until the pulsation subsides.     

Q: "I bought a used Fimco 55 gallon PTO sprayer. I have a John Deere 1025R tractor and want to use the sprayer to do broadleaf control, liquid fertilizer, and things like that. What roller pump should I use?" - Wes T.  

A: We recommend the Hypro 7560XL "Silver Series" Roller Pump. This pump has great flow and  pressure and is cast from a stainless alloy specially designed for pesticides and herbicides.

Q: "My rig is pulsing and has very low pressure. It will start spraying perfectly,but then go back down to low pressure. I tried cranking up the psi, but it didn't  work. I've been working with a very frustrating rig. Please help! There is no clog in gun isn't the issue. I think motor is going out, but maybe you can help" - Joe M.

A: Intermittent performance indicates that you may have a bad pressure switch. This switch is located on the front of the pump and has two red wires attached to it. Replacements switches are available for most models. 

Q: "I'm starting up our Hypro D503 for the season. It will build up pressure to 400 psi but when I engage the nozzle, it drops below 200 psi or lower but returns to 400 psi once the nozzle is turned off. I've checked and tightened all the connections. Cleaned the strainer on the intake and it's good. Thoughts?" - Chris T.

A: A drop in pressure when engaging the trigger normally indicates an air leak on the suction side. We suggest making sure the suction strainer gasket is set properly to form a tight seal and the bowl is not cross threaded or over tightened. You may also try watching the intake line to see if any air bubbles appear when activating the gun. 

If you've got a question about your spray equipment, leave it in the comment box below and we'll get right back to you.

Product Highlight: Hypro D30 Diaphragm Pump and GS40GI Control Unit

Posted by Sprayer Depot on Mon, Dec 21, 2015

Hypro diaphragm pumps are recommended for spraying herbicides, pesticides, liquid fertilizers, and many other hard-to-handle fluids. The Hypro D30 is one of Hypro's most popular medium pressure diaphragm pumps. Its low cost maintenance, and almost wear-free operation help make it the ideal choice for a wide variety of spraying jobs. This is definitely one of our top selling pumps, and the preferred choice for several of our small to medium-sized Kings Sprayers® models.

Interested in learning more? Let's look at the specs on this pump!



Need to control the pressure?

You can mount a control unit (also known as a regulator) on this pump for easy flow and pressure control of your sprayer system. Hypro GS40GI is a popular control unit companion for the D30. Installation is easy and we'll gladly mount it for you. Just let one of our friendly Customer Service Technicians know what you need.

Prefer to install it yourself? Follow these simple steps for direct mounting onto the pump:

  1. Locate the discharge flange port on the discharge manifold

  2. Using a 13 mm wrench, remove the nuts holding the flange manifold

  3. Remove the o-ring from the groove of the flange and install into the control unit flange

  1. Install the control unit onto the manifold where the discharge port had been previously

  2. Use the nuts previously removed to secure the control unit

  3. Install the hose barb outlets onto the control unit, making sure the o-rings are in place on the hose barbs

Just as every other part of your pump, the control unit also requires servicing and maintenance. If you need to repair the entire unit, order the repair kit and follow the instructions below to have it fixed in no time!

To repair a Hypro GS40GI unit, you will need the following tools:

Now let's get started! 

  • Repair Kit for Hypro D30 PumpUsing a ½ inch socket, loosen the 2 bolts that hold the regulator housing

  • Remove the regulator housing

  • Push out the valve stem with your fingers, releasing the 3 pieces

  • Using a pick, remove the popit

  • Using a hook, remove the revealed O-ring and plastic rubber seat 

  • Remove the metal seat

  • Replace the popit

  • You may need to use a pick to push in (around the edges)

  • Replace the plastic seat with the flat side going in first

  • The seat should be flush to the metal inside

  • Replace the O-ring, install the chrome piece and spring

  • There are 2 parts to the copper side; the larger side should be installed facing the top of the regulator

  • Replace the metal seat

  • Replace the regulator

  • Tighten the bolts using a ½ inch socket

Using the Regulator on a Diaphragm Pump

Posted by Sprayer Depot on Mon, Jul 27, 2015

You may already be expertly familiar with your pump’s pressure regulator, or you might be on the other end of the spectrum wondering how exactly a regulator works. You may call it a control unit or an unloader as these are often terms used interchangeably to describe the same part. Just in case you need a reminder, let's do a quick recap on what a pressure regulator does.

 A pressure regulator is responsible for maintaining a certain pressure rating in the discharge line. This allows excess liquid flow to by-pass back to a tank or drain. Basically, the regulator will cut off the flow of liquid at a certain pressure to ensure safety in various applications.

Using a pump’s pressure regulator is as easy as turning a lever to the right direction. However, not every diaphragm pump works the same so it is best to check your manual and follow the directions. To make it easier, we've created a simple infographic with steps on using the regulator on five of our most popular diaphragm pumps.

If you are interested in learning even more technical facts about pressure regulators/control units, take a look at our previous guest blog post highlighting 5 Ways a Control Unit is Better Than a Relief Valve.

In the meantime, check out our infographic below:


Even though using the regulator can be pretty self-explanatory, it pays to always check to make sure you are using it according to manufacturer's directions.

How To Remove a Pump from the Gas Engine and Gearbox

Posted by Sprayer Depot on Tue, May 05, 2015

HyproD30_copyWe’ve received a good amount of questions about how to remove a pump from the gas engine and gearbox on various sprayers. With so many pieces and sprayer parts, it’s easy to get hung up, especially if you forget to remove a bolt. Here we’ll talk through the process, mostly as it relates to the popular Hypro D30 pump.

Before we get started, here are the tools you’ll need to have on hand to make this run smoothly:

  • Wrench

  • Allen key (s)

  • Flat chisel

  • Hammer

  • Pry bar


First, undo the bottom drain plug at the bottom of the gearbox and drain the oil into a pan. Clean it all up and now you’re ready to disassemble.

Next, remove the five bolts that connect the gearbox and pump with the engine. There are four large bolts that face the pump and one medium size bolt at the bottom that faces the engine. Remove these five bolts and separate the two components. 

Tip: If you have trouble, this is where the flat chisel and hammer come into play. To get the separation started between the two components, lightly hammer the chisel into the crevice that joins the two components and you’ll have them apart in no time.

Set the engine to the side for a moment as we focus on the gearbox and pump that are still connected. Inside the gearbox you’ll see a gear and three bolts. Remove the three bolts. Then separate the gearbox from the pump. This will allow you to have better access to the pump and/or replace the pump altogether if necessary.

Tip: Use your flat chisel to hold the gear in place while you loosen the bolts.

To separate the other part of the gearbox from the engine, you’ll need to remove the four small bolts that connect the two components. Then you may have to enlist a variety of tactics to separate the two. You could turn the gearbox and using a rubber mallet gently tap the gearbox to loosen it. Another option is to use a pry bar or two to nudge the gearbox off the engine. Worst-case scenario is that you destroy the gearbox in the process and will need to replace the gearbox altogether.

Tip: Cut down a standard allen key that fits this size bolt. Having a shorter allen key will provide easier access to take the top bolts out.

Your Sprayer Needs an Oil Change Too

Posted by Sprayer Depot on Wed, Oct 22, 2014

We get it. There’s a ton on your plate and often some maintenance practices, like changing the oil in your sprayer, can fall by the wayside. Our technicians often get asked how often we recommend changing the oil in a pump crankcase. Of course, we defer to manufacturer recommendations, but thought it might be helpful to run through the process with one of our more popular pumps, the Hypro D30 Diaphragm Pump, especially as the sprayer season winds down.

For those of you unfamiliar with this product, Hypro diaphragm pumps come with oil in the crankcase. Unlike your vehicle, accessing oil in the crankcase take a little more effort.

The manufacturer recommends changing oil after 40 hours of break-in operation and then every three months or 500 hours, whichever comes first. So this means that you should change the oil in this particular model at least four times a year, if not more. Now Hypro recommends using its own brand of oil for this model - Hypro Oil (part number 2160-0038) is specially formulated, high-grade, nondetergent, SAE 30 weight oil designed to prolong pump life. 

Now that we have that covered, let’s talk about the three steps to changing the oil in your spray pump.

Step 1. After you’re done with your sprayer for the day, flush the pump with clean water.

Step 2. To drain the oil from the pump, remove the oil drain plug and rotate the shaft until the oil stops flowing out. If you have time to open the pump and inspect the diaphragms, now is a good time, but not mandatory.

Step 3. To fill the pump with oil, slowly pour the oil into the sight tube while turning the pump shaft. Turning the pump shaft purges all the air out of the crankcase. So you won’t have to deal with air bubbles or a less than full amount of oil. If you do decide to replace the diaphragms, always change the oil.

Part Number 66 is the Oil Drain Plug


Need a closer look? Check out the Sprayer Depot instructional video series on our YouTube channel where we dive into the whole repair process for a Hypro D30 pump here.

One quick note, for winter storage, which we’ll get into later here on the blog, or if you encounter freezing conditions, flush the pump with a 50/50 mixture of water and antifreeze. 

Lastly, keep in mind that most manufacturers recommend changing the oil in your pump every year, if not sooner. We’d actually go as far as to say that it’s highly recommended that the oil be changed at both the start and the end of the sprayer season so that any contaminants entering the crankcase can be removed before sitting in the pump all winter and that you get rid of any buildup from the off season.
