![]() Install the clean water for the test before spraying. ![]() Check whether leaks occur at the joints during use.The product comes with an inline filter to prevent nozzle clogging.Knapsack sprayer comes with a wide carry strap for easier and more comfortable carrying.A sprayer used in this way will need to be able to calibrate for those materials (fertilizers, pesticides and herbicides) that are being applied. Valves – A valve is a device that regulates the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passagewaysĪ knapsack sprayer is an agricultural tool that is used in spraying liquid materials such as fertilizers, pesticides, herbicides or even water.A pressure gauge properly calibrated, within the pressure range of the pump is provided on the discharge line to guide the operator in making a proper adjustment to the pressure at the site. Pressure gauge – It is a dial gauge that indicates the pressure at which the liquid is delivered from the pump.The size of the tank varies according to the pump capacity and the requirements It is usually made of metal sheet or synthetic rubber or plastic having good resistant quality against corrosion, erosion, and similar actions. Tank – It is the container to hold the chemical solution.Most hydraulic sprayers are equipped with positive displacement pumps capable of developing pressure, required for many spraying jobs. A pump displaces a volume by physical or mechanical action. Pump – A pump is a device used to move fluids, such as liquids or slurries, or gases from one place to another.Parts and functions of a knapsack sprayer In order to successfully use herbicides, their application must be accurate and uniform. With many new herbicides, the rate difference between effective weed control and crop tolerance is small. Herbicide efficacy and crop tolerance depend upon inherent species sensitivity to a herbicide and the size of the weed or crop at application. Understanding how to use them is essential for the successful application of agricultural chemicals, especially selective post-emergence herbicides. Knapsack sprayers are indispensable agricultural tools. Knapsack sprayers can be used to apply liquids such as fertilizers, herbicides and fungicides for example and is suited to spot treating areas. This products improve worker safety while simultaneously lowering the risk of environmental damage.Knapsack sprayer is a type of sprayer that disperses liquid through a hand-held nozzle that is attached to a pressurized reservoir carried on the operators back. They are highly suited for spot treatments and allows for better coverage of challenging target areas than traditional spraying.įurthermore, because they are designed for spot treatment, they use a lot less insecticide per acre. These products come in a simple and compact design which makes maintenance easy. They are both time-saving and energy-saving. They can be used for a variety of tasks, such as fertilizer or pesticide spraying, or simply watering plants. Our knapsack sprayers are reliable, efficient and durable. We have simple knapsack sprayers which require manual pumping for operation as well as motorized sprayers powered by a motor which is used to propel and operate it thus allowing the farmer to apply these chemicals with less labour. They are ideal for spot treatments and can be used to apply liquids such as fertilizers, herbicides, and fungicides. Knapsack sprayers are essential agricultural equipment and their use is necessary for the effective application of agricultural chemicals to reduce pests, weed and disease challenges.
