Pump Sprayers and Their Advantages


Pump sprayers can be used for paver sealer, concrete sealer, lawn care chemicals, and weed killer. It uses a piston pump as a propellant to spray through a nozzle. In order for the user to activate the sprayer they either have to pump it or depressurize it to release product. This can be done by taking off the pump head and pushing down on the plunger inside of the pump.

The pump sprayer’s activation method does vary by the type of design it has. Some sprayers use a hand grip while others use either a trigger or slide mechanism. Non-pressurized sprayers are the easiest to use because all you have to do is pull out the plunger and press down where it belongs before pumping up the sprayer. The non-pressurized sprayers are also the safest because they don’t have an integrated nozzle so there is no chance of a needle or blade being accidentally released into your hand when using.

What Can a Pump Sprayer be Used For?

A pump sprayer can be used for paint, paver sealer, concrete sealer, weed killer, and weed preventer. These sprayers come in both non-pressurized or pressurized models. The pump sprayer can be useful for painting a house, a fence, a shed, a patio, a wood decking item, a gazebo or any application where some type of coating needs to be applied with control. It can also be very useful for applying weed killer, fertilizers, and any other type of liquid chemical solution.

Non-pressurized sprayers are good for applying stains or wood sealers since they require some surface agitation to help the contents of the sprayer soak into the material. Since you aren’t able to pump up the pressure on this type of sprayer you can’t apply anything that requires a higher psi to be applied.

Using pump sprayers is also great because they are very lightweight and comfortable in the hand. Many of them have a looped design on the pump shaft so it’s easy for someone to attach a lanyard or some other type of straps or handle that makes it easier for someone to pump up the sprayer and carry it around. The features of some sprayers are sturdy wheels mounted, a large capacity tank with easy access to clean and fill, chemical resistant seals, and are easy to clean.

Most sprayers are very easy to use, such as the Chapin 1949, which some features include a large capacity tank and a 4 inch wide mouth for easy access to clean and fill, once the user knows how to activate them. It should be noted that there are some pump sprayer models that are more complex then others, and may be difficult to use if the user is not familiar with the model. If the pump sprayer attaches directly onto a container or pump tank then all you have to do is attach it and pump up the sprayer.


One should look for a pump that is easy to disassemble and reassemble with easy access to the filter and has a large capacity tank so there is minimal downtime treating the job site. Some handheld sprayers hold a capacity as little as a quart.

If you want to use a sprayer that attaches directly on the pump head then you will have to either pump it or depressurize it before setting. When depressing the plunger inside of the pump it creates negative pressure which in turn shuts off the flow through the pump head. Some pump sprayers use a pump grip while others can be activated via a switch or trigger on the pump handle. Some pump sprayers even have a switch to depressurize it and activate the flow.

How to Use a Pump Sprayer

The handheld sprayer tank is usually filled with concentrated powder or liquid and water is added to the desired dilution. After the pump is primed and the pump head attached, it is ready for use. When you want to apply a light coat of material simply pump up and spray, maintaining consistent pump pressure as you work.

To create more pressure or draw out a thicker substance always pump first then pull back on the pump handle. This action forces the pump shaft down putting pressure on the pump head which in turn forces product through the hose and nozzle.

Afterwards move the pump back up, reset pump handle lock, then pump downward or forward depending on the model to release desired volume.

Backpack Sprayer

These sprayers are designed to be carried and worn on the back like a regular backpack. The pump generally attaches directly onto the pump tank, pump head or pump handle for easy assembly. These pump sprayers are designed with foam shoulder pads and usually come with a nylon strap that can be adjusted into different lengths via a buckle.


Handheld Sprayers

Handheld sprayers are meant to be used when insecticides and disease-controlling chemicals need to be sprayed up close and personal. They’re small and lightweight, making them ideal for getting into tight places for accurate pesticide spraying on roses and other shrubs or can be used for indoor use watering plants. The top piston pump maintains pressure while remaining tiny and light. The pump handle and pump wand, which attach to the pump head, are specially designed for easy assembly.

Handheld sprayers can also be used in place of a garden sprayer when applying non-selective herbicides or weed killers. Handheld sprayers come complete with adjustable brass nozzles and chemical resistant seals so it will pump liquids directly from the tank, pump head or pump handle.

Handheld sprayers are easy to operate and are a great tool for spraying caustic chemicals.


Pump sprayers are designed to meet a wide range of demands, they are essential in the application of paver sealer, concrete sealer, weed control, lawn fertilization, and pest prevention. They must be refilled on a regular basis. Take great care to avoid spills while the sprayer is filled with the solution. The pump should be inspected for cracks, rust or leaks. The pump handle and pump wand should also be checked often to ensure proper assembly.

All sprayers require regular pump maintenance.  If the pump begins to lose pressure then the pump needs to be replaced. Most pump sprayer manufactures sell replacement pumps at affordable prices. A new pump will bring the sprayer back to optimal pressure levels so that you can pump product through the pump hose and pump nozzle.

Pump maintenance is more than just pump replacement.  It also includes pump inspection, pump output examination and pump assembly/disassembly. Pump sprayers are known for their mobility factor but sometimes users forget about the connections of the pump. In order for pump sprayers to come with a guaranteed output level, the pump hose and/or the pump nozzle need to be clean from all debris. Debris can obstruct the flow of water between the pump sprayer components and the filter, preventing the sprayer from operating correctly.

It is also important to check the filter and make sure it is free of any obstructions or blockages. If a pump sprayer is not maintained it can cause the pump pressure to drop significantly.


Sprayer Tank

For bigger tasks, manually increasing the sprayer pressure isn’t enough. For these applications and services, such as landscaping, pump sprayers with a large tank capacity are usually required to be used on the job site. The pump maintains pressure while liquid is transported through the pump hose and exits the nozzle on the pump wand.

Tank pump sprayers are larger than handheld pump sprayers and are designed to be carried on the backs of workers. They are typically used on a farm or for paver sealer and concrete sealer application services. They’re also used by landscaping and pest control businesses since they generally have a larger capacity tank than a hand sprayer and delivery is easier because the worker does not have to fill the tank as often. Be sure to always check the filter before spraying! Always clean and rinse the sprayer prior to its next use.

Garden Sprayers

The sprayer is made to reduce pump output. If it has a wand, handle, and nozzle then the output will be reduced. You can adjust the output of the pump by manually pulling on the plunger inside of the pump head.

Garden sprayers are designed for smaller applications on lawns, driveways and sidewalks rather than large scale environmentally damaging application.

Garden sprayers can be attached to pump head, pump handle and pump wand. A garden sprayer pump nozzle is designed with an adjustable brass nozzle so that it can release a variety of droplet sizes. By adjusting the pump nozzle, garden sprayers allow users to control the area they cover and the amount of paver sealer, concrete sealer, pesticide or fertilizer needed.

Adjustable sprayer nozzles are a great feature for garden and landscaping applications. Most lawn care chemical manufacturers recommend that pesticide or fertilizer be applied in a circular pattern, moving along the lawn from one section to the next. Paver sealer and concrete sealer should be applied in a non-overlapping sweeping motion. By adjusting pump nozzle, users can keep track of their movement around the yard, paver patio or concrete driveway by how much they have sprayed and where they began.


Nozzle Types

Most pump sprayers use brass pump nozzles or a wand with adjustable nozzles. Pump nozzles are designed to release a variety of droplet sizes. By adjusting the pump nozzle users can control the area they cover and how much paver sealer, concrete sealer, pesticide or fertilizer needed.

Spraying Pesticides

Wear protective clothing and avoid spraying into the wind when spraying pesticides, herbicides, finely-powdered chemicals, or other potentially hazardous materials.

Make sure the handle is in lock position before pumping the system.

Be aware of any special precautions when using a pump sprayer when applying pesticides which state “Do not use pump sprayers when spraying this product.”

Spraying Fertilizers

Follow all local regulations when disposing of chemical residues. Never use a chemical sprayer to fertilize or water plants. Never dispose of the remaining liquid or spray into a body of water where fish or animals live.

Weed Control

To prevent weed growth next year, spot spraying with pump sprayers is recommended in between installing concrete pavers, or rocks, before the landscaping is completed.

Cleaning the parts after use will help prevent any problems and pump nozzle problems for future use.


Pest Control

Pump sprayers are great tools for for pest control and some pest control services companies use them to spray chemicals. When applying pesticides that must be applied with a sprayer. Before you pump the pesticide from the pump sprayer, pump the handle back and forth five times to ensure the pump nozzle is clear of bugs. Pumping will stir up any insect or insects stuck in the pump nozzle so they can get pushed out.
