Maintaining and Servicing Your Roller Pump

Posted by Sprayer Depot on Mon, Nov 16, 2015

Your pump will last longer and perform at its best if you keep up with routine service. How often should you maintain your pump will depend on how often you use it and the type of liquid being pumped. However, there are general guidelines that the manufacturer recommends should be followed to properly maintain your pump.

Hypro Roller Pumps are some of our most popular pumps. They are used across different industries such as pest control, weed control, horticulture and other agricultural applications.

For those of you unfamiliar with this type of pump, Hypro Roller Pumps come in three different materials: Cast Iron, Ni-Resist, and Silver Series XL. They are compatible with a variety of liquids and chemicals, require no check valves and are budget friendly.

Before performing any type of maintenance make sure you follow these safety measures:

  • Pump should be disconnected from its electrical, hydraulic, shaft driven, or gas engine power source.
  • Do not perform service or maintenance to the pump, or attached components, until the pump unit is below 109°F (43°C). 
  • When handling Hypro pumps, wear steel-toed shoes and protective gloves in order to protect your feet and hands. Eye protection should also be worn.
  • Any hazardous liquids should be disposed of in a manner which complies with local and national regulations. Never dump fluids onto the ground.
Cleaning your roller pump after every use is easy and will prevent downtime. Flush the pump with a neutralizing solution depending on the liquid just pumped. Follow this with a clean rinse using fresh water. Don't forget to wipe down the pump after each use to prevent deposits from forming and damaging it.

When you are ready to store your pump for a long period of time, make sure to drain it thoroughly. Open any drain plugs, remove the suction hose and blow it dry with air. An antifreeze/rust inhibitor should be injected into the pump before both ports are plugged and the pump is stored. Plug all ports to keep out air until pump is used again.

Guest Post: Comparison of Roller to Diaphragm Pumps for Horticultural Spraying

Posted by Sprayer Depot on Thu, Oct 08, 2015

Most horticultural spraying equipment (those spraying fruits, vegetables, ornamental foliage, lawns, shrubs, and in nurseries) use either roller or diaphragm pumps. Here are some thoughts when considering which kind of pump to buy.

Match the pump to your spray material. Consult the chemical labels of the herbicide, pesticide, fungicide, or fertilizer you are pumping. Make sure you have the proper flow going to the spray nozzles or gun with enough flow left for agitation. Then match the flow and pressure to the pump performance chart. Do not buy a pump based on specifications shown on a price list. Consult the pump performance chart and notice that a pump will not perform at the max gpm and max psi. This is particularly true of roller pumps.

Match the pump to the duty. Roller pump life depends on the pump body material. Here is a rough estimate based on our tests:

Cast iron – 150 hours

Ni-Resist – 300 hours

SilverCast – 1000 hours

4001C_originalDiaphragm pumps, properly maintained, can last many 1000s of hours because the spray material is isolated from the drive components by a synthetic rubber diaphragm. We have seen them last over 30,000 hours. Plan on changing your diaphragms every 500 to 1000 hours of use, depending on rpm, psi, liquid pumped, and if the pump is flushed after use.

Analyze your costs. For example, both the 7560C cast iron roller pump ($154.55*) and the 9910-D30 diaphragm pump ($494.19*) will operate at 9 gpm/150 psi/ 540 rpm. The roller pump costs much less but will last a shorter time, which might make sense if you are spraying 50 hours per year. The diaphragm pump will have a higher initial cost but make sense if you are a commercial user pumping 1000 hours per year. Roller pumps can be repaired but it is difficult to predict if the repaired pump will perform close to new pump specs. For that reason, many worn roller pumps are scrapped. Diaphragm pumps will need the diaphragms replaced, but the pump will return to new pump performance.

Assess drive and plumbing. Roller pumps can run directly on a PTO shaft and will need a gear reduced engine or belts and pulleys for engine drive. The exception is 4101 series which can run directly on an engine up to 2600 rpm. Diaphragm pumps can run directly on a PTO and are available with gearboxes for engines. A relief valve, which is required for either pump, must be added to a roller pump system but is generally included as an attachment on a diaphragm pump.

If you have any questions consult the experts at Sprayer Depot.

5 Signs of Roller Pump Wear

Posted by Sprayer Depot on Wed, Apr 01, 2015

7560C2014SchematicWe’ve talked a little bit about roller pump repair in the past and briefly explained some of the things to consider if you think it's time to consider repairing a broken or damaged roller pump. Today we’ll dive into the subject in more detail and share what to do to carefully inspect all parts of the roller pump for wear. From there you’ll be able to easily assess whether a repair kit is in order or, alternatively, if a full replacement pump is on your to-do list. Let’s get started.

When you’re looking for signs of wear, here are five areas to start. We’ll be using a Hypro roller pump as a point of reference throughout, but the main points apply to any make or model.

Housing Wear: The first place to look for wear is the housing. Make sure it’s in good condition, checking on both the inside diameter and the back face. Check 1/16” from the edge and look for a lip as an indicator of excessive wear.

Cover: Checking the cover might be the first place that you’ve looked for signs of wear. And well you’re not far off. When looking at the cover, keep an eye in the roller area in particular.

Rotor: When you’re looking at the rotor for signs of wear, you should look at its size. An undersized rotor, or one with worn roller slots, is a sign of excessive wear. To determine if it's undersized, you’ll want to measure the thickness of the rotor, which on a Hypro 7500 series roller pump should be 1.4995 at its smallest.

Rollers: Much like the rotor, undersized or swollen rotors in both length and diameter are not good. Measure the thickness and make sure it’s no smaller than 1.4995. Any smaller and it may be worn out and need to be replaced. Oh and make sure you replace rollers as a set, not just one at a time.

Shaft: Check the drive end of the shaft for wear (as well as in the seal area ) where signs of excessive wear include pitting or grooves. If it’s worn or pitted, the shaft needs to be replaced. Otherwise, it won"t seal properly.

After the above parts have been checked and the various points have been considered, decide if the pump is repairable. If it’s just a repair, grab yourself a repair kit and the following tools: socket, hammer, cradle (to support the housing), file and a measuring tool, to name a few. Then follow these steps to disassemble the pump: 

  1. Remove the adapter from the pump shaft.
  2. File off any burrs on the pump shaft.
  3. With a screwdriver, pry bearing covers off of the endplate and body.
  4. Remove the endplate bolts.
  5. Support the pump at its ports in a support fixture with the endplate down. Place it on a press bed. Center the press on the pump shaft and apply pressure to press the pump apart. Note that the shaft and rotor will remain with the endplate.
  6. Remove the rollers and endplate o-ring seal.
  7. To disassemble the rotor from the shaft, place the endplate in the support fixture with the rotor down. Center the 3/8" bolt on the pump shaft and apply pressure to press the shaft out of the bearing.
  8. With the endplate in the support fixture and the front of the endplate facing down, center the bearing support tool and slowly press the bearing out of the casting. Repeat the procedure to remove the bearing from the pump body.
  9. Punch the seals out of the endplate and body with screwdriver and hammer. Then discard the seals – seals can’t be removed without damaging them so you’ll need to replace them regardless.

Once the necessary repairs have been made and the pump is clean of debris. Reassemble the pump. Note that when you’re tightening the bolts tighten them in a crisscross pattern. Then check to see if the rotor is centered in the pump case by turning the pump shaft by hand. If the pump turns hard, place a wooden dowel against the end of the shaft, centering it on the shaft not the bearing. Tap lightly with a hammer. Try turning the shaft again and if it turns more easily you should be good. If this doesn’t do the trick, repeat the steps and tap the other end of the shaft. These minor adjustments will ultimately align the shaft, but if that doesn't work, try cleaning the pump - it's possible a piece of debris from a rag or something is caught inside.

Now that your roller pump is back in action, take care to ensure it lasts longer and performs better by taking care of it properly. After each use, make sure that you flush the pump with a neutralizing solution that's meant for the liquid you just pumped. Follow with a clean water rinse. This is especially important for corrosive chemicals. It is good practice to clean the pump after each use to prevent deposits from forming and damaging the pump.

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.

Guide to Pump Repair Kits and Routine Maintenance

Posted by Sprayer Depot on Tue, Jun 24, 2014

We are halfway through spray season and you know what that means, time for routine maintenance to keep your sprayers working like a well-oiled machine. Most manufacturers recommend this regular upkeep every three months, with more attention needed during this heavy use time of year. Here we’ll cover three sprayer pump types – diaphragm, centrifugal and roller – and provide the information you need to know to ensure smooth operation for the remainder of the season.

Hypro D30 Pump                   Hypro Roller Pump                    Hypro Roller Pump 7560

First, you’ll need a pump repair kit. Repair Kits are unique for each type of pump and include durable items intended to repair components that see more wear-and-tear or need extra attention every few months. You will notice o-rings, seals and diaphragms in these kits, among other components. So let’s take a closer look:

D30 Diaphragm Pump Repair Kit (Item #9910KIT1724)  

  • Hypro recommends changing diaphragms every 3 months or 500 hours.

  • Watch this video for a closer look at how to install a pump repair kit.

  • If the oil in the sight glass on the pump turns a milky color or oil comes out of the discharge port you most likely have a diaphragm rupture.

  • Diaphragms are the main wear part on the pump and separate the oil-filled crankcase from the chemical you are spraying. Failure to change diaphragms regularly, or run the pump with ruptured diaphragms, will cause pump failure – and a lot of headache.

7560 Series Roller Pump Repair Kit (Item #34300381)

  • Roller pump repair kits include new seals, rollers and o-ring for the endplate.

  • If your pump does not prime or experiences loss of pressure, this can be caused by stuck rollers or seals leaking air. If the pump shaft will not turn there may be solid objects caught inside the pump or the pump itself may need to be replaced.

  • Before ordering a repair kit, press the pump apart and inspect the body and endplate for lips or indents. If you find lips or indents the pump will need to be replaced. If the body and endplate are in good condition, installing a repair kit will have the pump running to specs.

Hypro Cast Iron Centrifugal Pump Repair Kit (Item #34300332)

  • Centrifugal pump repair kits include the mechanical seal, flat gasket and body o-ring.

  • If liquid is leaking out of the weep hole on the pump this indicates the seal is worn. This can be caused by running the pump dry or from failure to flush the pump out after use.

  • If you are experiencing low discharge output the impeller might be scarred or clogged. Impellers are not included in the repair kit, but are sold separately.

All in all, a pump repair kit is ideal to properly care for your sprayer and this simple routine maintenance will alleviate any frustration or delay in work. While you’re taking a closer look at your sprayer, check all washers and gaskets to prevent leakage, and spray hoses should be inspected under high pressure by using plain water periodically during the heavy use season. Once you’re done you’ll be happy to have invested the little bit of time to keep your sprayer in optimal working condition.

Common Causes of Pump Failure

Posted by Marketing Manager on Fri, Mar 21, 2014

Contributed by Guest Blogger:  John Lang, Hypro

Three Steps to Prevent Pump Failure

Your pump can fail or become inoperative when left dormant for long periods of time. The elastomeric (rubber) components, when left in a compressed state, will take a “set”. When this happens the rubber components deform to their compressed state  over time and don’t properly respond when brought back into service. The rubber components are also susceptible to “drying out” when stored without liquid in them. The elastomers don’t actually dry out but some chemistries that have come in contact with the elastomer can react with air and become hard and brittle.  To prevent these types of failure during seasonal storage perform these three operations.  
 Hypro Pump
  1. Adequately flush the pump and solution system to remove all residue of chemicals. Check the label of the chemicals used for recommendation on what agent should be used to best clean and neutralize the sprayer components.
  2. To prevent oxidation of components it is always good practice to fill solution system components with some form of antifreeze and spray a small volume through the system (from tank to nozzle). This procedure will prevent elastomer components from “drying out”.
  3. Leave regulators and unloaders in a loose or open state so that they don’t stick on startup and fail the pump.

Kings 3 Point Hitch SprayerGet it Ready

When pulling the sprayer out and getting it ready for operation be aware that the pump is dependent upon the proper functioning of the system components. Perform these three steps to check the system out before going to full on operation.
  • Check maintenance schedule for pump. The best time for maintenance is before the season begins when the system is clear of hazardous chemicals.
  • Cycle unloader valves and pressure regulators to be sure they are not stuck in place. If you feel the component is not free perform service on the component.
  • Check pump to see that it is not stuck. If the pump is driven by a mechanical drive, rotate the pump by hand to check that pump is free. An electrical driven pump that has a closed couple drive should be run in short bursts to determine that pump operating as expected. Always set the sprayer to a low pressure setting for initial startup and check sprayer for leaky joints.
Performing these simple checks early can help you achieve the timeliness of your application when it is needed.

The Pump You Want vs. The Pump You Need

Posted by Marketing Manager on Fri, Sep 14, 2012

A Guide to Hypro Pumps

Contributed by guest blogger:  Mark Techler, Techler & Associates

Use this helpful guide to match your sprayer application with the proper Hypro pump. For example, if you need to spray 30 gpm at 50 psi and need the pump to last 1000s of hours, it may be more cost effective to buy a centrifugal pump rather than a roller pump. Hypro Centrifrugal Pump

Or, if you have been using a piston pump and are seeing excessive wear due to pumping abrasive liquids, you may want to consider a diaphragm pump. If you are running your centrifugal pump dry and destroying the seal, a self -priming centrifugal pump may be a good option.
