To select a high pressure spray gun for agricultural spraying, match the gun’s pressure and flow ratings to the pump and nozzle, then check whether its materials, controls, and connections suit the chemical and working conditions. Do not choose by maximum pressure alone: the system must deliver the flow and spray pattern required for the target crop or cleaning task while staying within every component’s rated limits. Before requesting a quotation, prepare your operating pressure, available flow, chemical details, hose connection, and expected quantity.

This guide is for agricultural equipment manufacturers, distributors, farm operators, and procurement teams sourcing high pressure spray guns. It is relevant when specifying equipment for tasks such as crop spraying, orchard applications, livestock-area cleaning, and equipment washdown. These uses can require different pressures, flow rates, spray patterns, and chemical-contact materials, so one configuration should not be assumed to fit every job.
A high pressure spray gun is a handheld control device fitted between a pressurized fluid supply and a nozzle or lance. The operator uses the trigger or valve to start, stop, or regulate the spray, depending on the gun design. The nozzle shapes the discharged liquid, while the pump and upstream plumbing determine the pressure and available flow delivered to the gun.
In agricultural systems, the gun is only one part of the application setup. Pump capacity, hose length and condition, filters, pressure regulators, nozzle selection, and liquid properties can all affect performance. A gun cannot compensate for an undersized pump, a blocked filter, or a nozzle that is unsuitable for the target.
Common selection points include a straight lance, an adjustable-pattern nozzle, or an interchangeable nozzle arrangement. A narrow pattern may be useful for a concentrated stream, while a wider pattern can cover more area at a shorter distance. The actual pattern and droplet behavior depend on the nozzle design, pressure, flow, and liquid, so confirm the intended result with the supplier rather than relying on a product label alone.
Consider whether the application needs a trigger lock, adjustable flow, a swivel connection, or a lance that provides greater reach. These features can affect handling and compatibility, but they do not replace correct operating procedures or protective equipment. Confirm whether the gun is intended for continuous or intermittent use under your operating conditions.
Identify every component that contacts the spray liquid, including the body, internal valve, seals, nozzle, and fittings. Material suitability depends on the chemical formulation, concentration, temperature, and exposure duration; a material described as corrosion-resistant is not automatically compatible with every agricultural chemical. Share the product name or safety data information with the supplier and ask for compatibility confirmation.
Also consider exposure to outdoor storage, moisture, dust, and impact. Metal components may offer durability for demanding handling, while polymer components can be suitable in some configurations, but material choice should be based on the actual operating environment and verified specifications. Avoid assuming that two guns with similar external appearance have identical internal materials.
Request the gun’s rated working pressure, maximum permitted pressure, compatible flow range if specified, temperature limits, connection type, and seal materials. For reference, 10 MPa is equivalent to 100 bar; use the same pressure unit when comparing the gun, hose, pump, and fittings. The lowest-rated component sets a practical limit for the assembled system, so confirm the rating of the full fluid path.

Flow should be considered alongside pressure. As a simple illustrative calculation, if a pump supplies 20 L/min and one branch uses 15 L/min, only 5 L/min remains for other branches before accounting for system losses. This is an example for planning, not a recommended spray rate; actual demand must be based on the pump curve, nozzle data, and application requirements.
For crop spraying, define the target, coverage area, distance, and desired spray pattern before selecting a gun. Crop type, canopy structure, wind conditions, chemical label directions, and local application requirements may influence the nozzle and operating method. High pressure does not by itself guarantee better coverage or lower drift.
For orchard or taller-canopy work, reach and pattern control may be important, but the operator must still be able to apply the liquid in a controlled manner. For equipment or livestock-area washdown, the main priorities may instead be cleaning reach, trigger comfort, and compatibility with the cleaning solution. Treat these as separate applications when the required nozzle, materials, or duty cycle differs.
Pricing depends on the selected configuration, materials, nozzle and accessory requirements, order quantity, and any customization. Minimum order quantity and lead time can vary by model and production schedule, so request current terms rather than assuming standard availability. For a useful quotation, specify the intended application, target quantity, delivery destination, connection requirements, and whether samples or drawings are needed for evaluation.
Ask suppliers for a clear specification sheet and confirmation of the pressure rating, connection details, wetted materials, and available nozzle options. Check whether they can review your pump and application information, explain any configuration limits, and clarify packaging, spare parts, warranty terms, and order conditions. If a specification is not documented, request written clarification before approval.
For agricultural equipment sourcing, communication and configuration accuracy matter alongside unit price. A supplier should be able to identify what information is still needed and avoid promising compatibility without reviewing the liquid and operating conditions. Kobold can discuss high pressure spray gun requirements with buyers and help assess product configurations against the details provided; final suitability should be confirmed against the selected product specifications and the complete system.
The right high pressure spray gun is the one that matches the application, pump output, chemical exposure, and connections—not simply the one with the highest stated pressure. Begin by documenting the target task, operating pressure in bar or MPa, required flow in L/min, chemical details, hose connection, and expected order quantity. Then compare documented specifications and confirm the complete system ratings before purchase.
To request a Kobold quotation or configuration discussion, send your application description, pump pressure and flow, preferred nozzle pattern, chemical information, connection details, and estimated quantity. These details give our team a practical basis for reviewing your requirements and identifying questions that should be resolved before sourcing.
