Product Highlight: Diaphragm Pumps

Posted by Sprayer Depot on Fri, Feb 03, 2017

Having the right equipment to get a job done is essential to making sure that projects get done efficiently. Choosing the right diaphragm pump is no exception. Costly equipment repairs and lengthy downtime can disrupt the day-to-day operation of your business so it’s important to evaluate product options thoroughly to make the best possible purchasing decision.

Uses for Diaphragm Pumps

Diaphragm pumps are used extensively in many industries and can handle a very wide variety of liquids. Diaphragm pumps can transfer liquids with low, medium or high viscosities and also liquids with a large solids content. They can also handle many aggressive chemicals such as acids because they can be constructed with a wide variety of body materials and diaphragms. They are especially popular for high-pressure tree spraying and lawn spraying.

Cost, quality, maintenance, shipping time, product warranty and reviews are important things to take into consideration when choosing a diaphragm pump so be sure to evaluate your needs carefully and compare pump options across a few different brands or manufacturers.

In this post we'll take a closer look at a few of Sprayer Depot’s most popular diaphragm pumps:

Tall Tree Spray Guns

Posted by Sprayer Depot on Fri, Feb 26, 2016

When you have to spray tall trees, it is advisable to use professional spray equipment. However, not just any spray equipment will do. You need something capable of outputting the necessary pressure to ensure uniform coverage. Today there are many high quality professional spray guns designed specifically for spraying tall trees. These guns enable you to prevent or combat pests and disease without leaving the ground.

Let's take a look at three of our most popular tall tree spray guns:

FMC John Bean 785 Spray GunFMC 785 Tall Tree Gun

Max Flow: 48 gpm

Max Pressure: 800 psi

This spray gun is adjustable from a fine spray mist to a solid stream by a mere twist of the wrist!


Udor Long Range Spray GunUdor long range spray gun.jpg

Max Flow:30 gpm

Max Pressure: 850 psi

This UDOR high performance spray gun with a 21" barrel features a 12 mm internal tubing with stream straightener & adjustable spray pattern from straight stream to cone mist.

Max Flow: 25 gpmUdor turbine spray gun.jpeg

Max Pressure: 850 psi

This tall tree spray gun features a 17" barrel, 10 mm internal tubing & adjustable spray pattern from straight stream to cone mist


Your choice of chemical treatment will vary depending upon the issue you are addressing such as pest infestations or disease. Place the chemical treatment into the container of the high-pressure sprayer, following manufacturer directions.

Spray guns give you control and flexibility so you have a wide range of motion. Hold your spray gun in such a way that you can spray the tree at an angle and avoid spraying chemical on yourself. Don't forget your Personal Protective Equipment (PPE), whenever you use chemicals. It is also advisable to cover lower vegetation with plastic sheeting to protect it from any damage from the chemical treatment.

When you start the sprayer, you will be able to control the flow of the spray with your sprayer gun. Position the gun and adjust the speed so that you can send a focused stream into the tree branches to coat leaves and branches with a fine mist of the sprayed chemical. As you spray the tree, walk around so that you can reach branches and leaves from all angles for proper coverage.

Let us help you make your application as effective as possible. Let us know the type of tall tree you are spraying and what chemicals you are using and we can help you get the best equipment for the job!

3 Reasons Why You Should Buy a Pump from Sprayer Depot

Posted by Sprayer Depot on Wed, Aug 20, 2014

You’re on the market for a new spray pump. You have a pretty clear idea of what you need. After all, nine times out of ten it’s a replacement pump that’s on its last leg and in need of replacing. Not an easy pill to swallow when you have to buy one of the most vital parts for your sprayer. But where do you start?

Does this scenario sound familiar? Since we're more focused on your needs than your wallet, here we’ll share three foolproof tips to get you the best product for your needs at the best price. 

Tip #1: Inventory
Whether you’re in the market for a diaphragm pump, roller pump, centrifugal pump, piston pump, transfer or plunger pump, find a retailer that covers the spectrum with a variety of brands on hand for sale. Look for a retailer that carries major sprayer pump brands like Hypro, Udor, Comet, Banjo, Myers and SHURflo, to name a few. Since not all brands manufacture all pump types, at Sprayer Depot you’ll find a better selection for your needs and a more knowledgeable team to answer any questions. Sprayer Depot carries all the major brands for practically every type of spray pump at the best price.


Tip #2: Price Matching
Speaking of price, don’t be afraid to shop around. You’ll find out more about the product you’re looking for from kicking the proverbial tires at a few shops before settling on one. That will also give you a chance to scope out who has the best pricing policy – for example Sprayer Depot will match any competitor’s price (must be an authorized dealer/distributor). We strive to offer the lowest price on all major spray pump brands, but if you happen to find a lower advertised price from an authorized distributor, Sprayer Depot will match or beat that price! When you’re shopping for a part like a pump you know your going to have to spend a pretty penny so why not get the best deal.

Tip #3: Customer Service
You’re a pro so the customer service team from any retailer won’t show you how to do your job, but they can offer some insight into the latest tricks of the trade. At Sprayer Depot, our knowledgeable customer service technicians have more than 55 years of combined experience in the industry. Many of them have worked their way into the role through production jobs building the very sprayer you use today. So they know their stuff and speak your language. Plus, they’re not sales guys aiming to make commission – they genuinely enjoy what they do and strive to assist folks in finding the product that’s best for their needs.

So the next time you’re in the market for a spray pump, or really anything for your sprayer equipment, remember to consider inventory, price match policies and customer service. Better yet, just give the guys at Sprayer Depot a call or visit the online store. You’ll be in good hands.

Diaphragm Pump Maintenance: Looking Beyond the Pump.

Posted by Dan Rose on Wed, Jun 22, 2011

Diaphragm Pump Rebuild?

How long should a Diaphragm Pump last before needing a rebuild kit?  The quick answer is a full season.  Keep in mind that the time frame may vary depending on the amount of time it's used and the type of chemicals that are sprayed.

Diaphragm rebuild kit

Beyond the Pump

If your pump needs to be rebuilt every 3 months, you may have an intake restriction issue. To illustrate what an intake restriction will do to your pump, try drinking though a coffee straw at the same rate as you would a regular soda straw.  The feeling you get in your head as your tongue gets vacuumed to the roof of your mouth is the same stress your pump endures when the intake line is restricted.  If you continue to drink though the small coffee straw at a consistent rate, eventually you will develop a headache or maybe even pass out.  Either way, you will STOP.  Your Diaphragm pump will do the same thing; it is going to stop sucking (no pun intended).

Follow this checklist to make sure your Diaphragm Pump stays in good working condition:

  1. Check the strainer to make sure they are clear and the holes are not plugged
  2. Check the size of the strainer mesh if you have a high flow pump. Over 7GPM, mesh size should be 20-30
  3. Check the intake hose diameter 
  4. Make sure that the bottom of your tank is free from chemical build up and debris
  5. If you have a homemade jalopy pump with a long intake line, make sure there are no kinks in the line

If you need a rebuild kit for a Hypro, Kappa or any other pump you can find them on the right side bar of the pump you select on our website.  Or you can go to our home page  to view our complete product line.
