You need to consider several factors when choosing the best pump sprayer.

A hand-pumped sprayer consists of a 1- to 5-gallon plastic or stainless steel tank, a manual (hand) or electric (powered by batteries) pumping system, and a long wand attached to the nozzle. It has adjustable or interchangeable nozzels that allow the user to control the pattern of the spray. Hand-pumping sprayers are available in one-handled and two-handled models, backpack options, large but portable wheeled models, and even self-propelled models.

Sprayer Types

  • Backpacking sprayers: These types of sprayers have tanks that hold more liquid than hand held ones, making them easier to transport.
  • Attaches to the end of a garden hose and combines the liquid ingredients as the liquid flows out of the nozzles. Because the mixture is concentrated and there is an endless supply of liquid, this kind of sprayers is ideal for covering large surfaces.
  • A hand held spray bottle is an easy way to get rid of pests without using chemicals. It can be used for small jobs like spraying plants or for larger ones like cleaning up after pets.
  • Handheld sprayers: Handheld sprayers feature a large reservoir filled with water, which is then pumped through a hose and nozzle into the air. These types of sprayers are
  • Battery-operated sprayers: A battery-operated sprayers can replace the manual actuation of a conventional spray gun. These devices work by means of an electric motor that forces air into the reservoir to pressurize the fluid inside. They may also include a solenoid valve that allows the user to manually control the flow rate of the spray. In addition, they may come equipped with a shutoff mechanism to prevent accidental spraying.

Pump Style

Spray guns come in two basic types: those that operate with an air compressor and those that operate with a power source such as electricity or gas. Air powered sprayers require the operator to push down on a lever or button to force compressed air into the gun. When the operator releases the button or lever, the compressed air pushes the liquid through the nozzle. Electric powered sprayers use a small electric engine to create the high pressures needed to force the liquid through the nozzle; these units can also be operated remotely via radio control. Gas powered sprayers use a mixture of propane and oxygen to produce enough heat to vaporize water and propel it through the nozzle.

Size and Tank Capacity

Pumps vary in their wand lengths and tank sizes. A longer wand allows for better accuracy and control.

The size of the tanks determine how long the pump spray can run without needing a refill. For backpack sprayer, the capacity is usually between 3 and 6 gallons; for hand held sprayer, it’s usually between 1½ and 2 gallons.


To withstand the fertilizers and chemicals that come out of these pumps, most sprayers use heavy duty plastics that have wands made from brass, aluminium, or stainless steel. Some sprayers even include stainless steel tank options.

While plastic nozzles are bester than metal ones, they tend to wear out faster and break easily. Metal nozzles, however, are usually made from stronger materials and don't break down as quickly.


Since the user needs a pumping mechanism to move fertilizer through his/her garden, it is important to consider how much pressure is needed to do the job. Fertilizer comes in various forms; liquids, granules, pellets or dust. Each type requires a certain amount of force to push them out of the container. For example, if you were to pour 1 cup of dry fertilizer into your garden, you would need about 15 lbs of pressure to get it out. You can also measure the pressure of the liquid fertilizer in gallons per minute (GPM). One GPM equals one pound of pressure applied every second. So, if you had a 10 GPM hose running into your garden, you could apply about 100 lbs of pressure each second!

Handheld sprayer: Lightest (about 5 lbs), backpack sprayer: Heaviest (about 12 lbs), wheeled sprayer: Largest (about 15 lbs).


The nozzled determine the type of the aerosol and the amount of the liquid sprayed. Most aerosols come equipped with a number of nozzled that vary in size and function. Some nozzled are designed specifically for spraying foam, others are used for applying liquids. Nozzled may be adjusted to control the flow rate and the direction of the mist.


Many sprayer types are designed for various purposes, including weed management, lawn fertilizers, pest controls, and so forth. They may need to be periodically refills, cleaned, and maintained.
