Electric Backpack Sprayer Field King Professional 190328

Recognize with this electric backpack sprayer there is no pump machine, so one hand can operate the spray wand. 5 to 10 psi works great for dispensing foam. This is particularly important when spraying herbicides because off-target spray can harm desirable plants and waste expensive herbicides. Pressure from about five psi to 13 psi works excellent for the shower. The sprayer can also quickly be transformed into a foam container. The backpack sprayer will operate on ultra-low pressure. The backpack sprayer will have all sorts of other great features, many of which are shown in the

• The pressure can be calibrated in increases of 0.2 psi and from 1.5 psi to 12 psi.
• Pressure from about 1.5 psi to 10 psi works great for managing foam.
• Pressure from about five psi to 13 psi works excellent for spray.

Lower Output - Electric sprayers are lower output or volume (as measured in gallons per minute or GPM) than gas-powered sprayers.

Here are two examples:

The spray hose is old and soft, it swells to an appropriate pressure, and there is no pressure left to push the water through the tube. The spray hose wound too tightly on the reel, and the pump doesn’t have sufficient pressure to push the water through the squished down tube.

Volume Pressure Tradeoff – In addition to generally having less volume and less pressure than gas-powered pumps, electric pumps usually have a significant tradeoff between size and weight. On the other hand, gas-powered shoes are available in high volume, high pressure if needed (for example diaphragm pumps).

Transferring backpack sprayer to another Vehicle – Electric pumps are usually wired to the truck battery. We recommend these pumps are run off a separate battery (not the truck battery), or the vehicle is left running while the pump is on. If the pump is moved from the pump series, the battery will run down, and the pump motor will begin running hot.

Pros & Cons of Electric Power Sprayer:

Electric sprayers aresimpler, have fewer parts and cost significantly less than gas powered ones. Regularly, the pump and motor are a single unit, which costs less and doesn't require additional assembly, which saves labor and cost.
Electric sprayers take up less space in a vehicle. The electric pump and motor are usually significantly smaller than a gas motor and pump assembly.

• No noise
• Lower output or volume
• Provide lower pressure
• Aren't suited for long distances pressure washer
• Occasionally, spray hose problems can occur with low-pressure
electric pumps
• The pressure switch senses demand and turns the pump on
• The spray hose is wound too tightly on the reel, and the pump doesn't have enough pressure to push the water through the squished down hose
• In addition to generally having less volume and pressure than gas-powered pumps, electric pumps usually have a significant tradeoff between volume and pressure
• You can find a higher pressure electric pump, but it will be lower volume
• On the other hand, gas-powered pumps are available in high volume, high pressure if needed - diaphragm pumps, for example
• Electric pumps usually are wired to the truck battery, so it's more involved to transfer the spray the rig to another vehicle - the vehicle requires service, for example

This book doesn't address or recommend vendors or models, but generally speaking: Smaller pumps are more reliable and draw fewer amps, which means they won't kill the truck battery.
The downside to these pumps is the pressure demand switch is usually a weak point that fails about once a year.
