Sprayer pumps with flow rates from 40 to 49.9 L/min

Spray pumps are indispensable tools for distributing liquid products such as fertilisers, fungicides, herbicides, and pesticides in agricultural activities. These devices ensure uniform and precise coverage of crops, increasing work efficiency and reducing waste of resources. There are different types of spray pumps, each designed to meet specific needs.

• Backpack spray pumps (backpack or shoulder strap): Backpack (or shoulder) sprayers are synonymous with comfort and agility at work and are among the most widely used machines in the world precisely because of their convenience and ease of use. In fact, in these models, the tank is equipped with two practical shoulder straps that allow the operator to wear it like a real backpack and carry it freely throughout the area to be sprayed. In this category, you can purchase a battery-powered pump rather than an electric or manual backpack pump. This type of pump has a limited tank capacity, which in most cases does not exceed 20 litres, and in terms of power, which, particularly in manual models, depends entirely on the frequency of 'pumping' that we perform by directly acting on the lever.
• Spray pumps with trolley and tank: The wheeled spray pump is an excellent solution if you need to work without having to carry a heavy load, as is the case with backpack or shoulder pumps. The pumps are mounted on a trolley that is then pulled manually or with agricultural machinery, such as a riding-on mower, throughout the entire work area. This type is ideal for those who need to spray surfaces of medium and large sizes, such as orchards, parks or large vegetable gardens, and require a significantly larger tank than shoulder, shoulder strap or trolley models. The wheelbarrow sprayer pump can be fitted with a tank starting from 50 litres and a power ranging from 18 to 45 bar.
• Spray pumps and motorised spray pumps (pumps only): Motorised spray pumps are used to treat crops and, thanks to their high operating pressure, they atomise the product to the maximum. The range of spray pumps that AgriEuro presents in this category is among the most extensive on the market, with around 30 products divided by power supply and type.

A spray pump is an essential piece of equipment for anyone who has a vegetable garden or garden, large or small, with flowers, trees or fruit plants. Those familiar with spray pumps know how indispensable this tool is and how important it is for carrying out periodic treatments on plants, spraying liquid substances that act as protective against all kinds of pests, insects or fungi.

We are talking about normal treatments, the same ones that are also required in so-called 'organic' farming, whether professional or just as a hobby, and which are necessary for the healthy growth of the plant.

Spraying pumps are therefore used to administer herbicides, fungicides and treatments to plants, flowers and crops of various kinds.

Generally, when we talk about 'weed control pumps', 'sprayers' or 'sprayers', we are referring to any agricultural machine that is:

• Capable of spraying chemical or biological herbicides;
• Composed of a tank (or barrel), a lance and a manually operated pump (as in some more traditional backpack pump models), battery-powered (battery-powered spray pump), electric, combustion engine (spray pump or motorised spray pump) or tractor-mounted

Spray pumps are complex devices composed of several elements that work together to offer optimal performance in various application contexts. The operation of spray pumps varies depending on the type of power supply and configuration, but the main components remain common to all types.

• Tank: The tank is the container that stores the liquid to be distributed. Tank capacity can vary from smaller models with 1 litre to larger models that can hold over 20 litres. The choice of capacity depends on the size of the area to be treated and the desired refill frequency.
• Pump: The heart of the device, the pump is responsible for pressurising the liquid. There are several types of pumps: piston pump, mini diaphragm pump, diaphragm pump.
• Power supply: spray pumps can be manual, battery-powered, electric, combustion engine or tractor-mounted.
• Nozzle: The nozzle is the element from which the pressurised liquid is released. It can be adjustable to vary the type of spray, allowing for uniform and controlled distribution of the product.
• Lance and hose: The lance is the component used to direct the liquid jet, while the hose connects the lance to the pump. The length of the hose can vary, with models offering hoses from 12 metres to over 100 metres to reach distant areas without moving the pump.
• Control valve: This valve allows you to control the pressure and quantity of liquid dispensed, ensuring precision in application.

The operation of spray pumps begins with filling the tank with the liquid to be distributed. Once the device is turned on (manual, battery-powered, electric, petrol-powered or tractor-mounted), the pump pressurises the liquid, which is pushed through the hose to the lance. The operator can adjust the nozzle to obtain the desired spray pattern, whether it be a fine spray for light coverage or a wider spray for denser distribution.

Battery-powered and electric spray pumps offer the added benefit of quiet operation and low environmental impact, while petrol pumps provide power and autonomy for intensive work. Tractor-mounted pumps are ideal for covering large surfaces without the need for frequent refilling.

Spraying pumps offer numerous advantages that make them indispensable tools for agriculture and gardening. Here are the main advantages listed and described.

• Uniform distribution: The ability to dispense liquid evenly over the entire treated surface, ensuring effective application.
• Pressure adjustment: Allows the liquid flow to be adapted to the specific requirements of the treatment, improving effectiveness.

Tank capacity

Another important aspect to consider is the tank capacity, which is usually between 10 and 25 litres in smaller models, such as shoulder, trolley or backpack pumps, and up to 6000 litres for self-propelled models.

Weight

Especially for shoulder-mounted models, it is very important to consider the actual weight of the machine with a full tank when purchasing. This will allow us to make a more accurate prediction of the actual comfort of the machine in operation and to assess whether it requires excessive effort on the part of the user to manoeuvre. Remember that most backpack sprayers weigh between 6 and 20 kg.

Number of diaphragms

The number of membranes in the pump varies from 2 to 4. The membranes are essential components for the operation of the pump as they create the pressure necessary for the delivery of the liquid.

Flow rate

When we talk about the flow rate of a spray pump, we are referring to the volume pumped, i.e. the volume of liquid delivered by the pump in a given time interval, which is usually indicated in litres per minute (L/min), gallons per minute (gpm) or cubic metres per second (s.q. m).

Maximum pressure

One of the most important characteristics of a sprayer is pressure, i.e. the force that the machine exerts on the pumped liquid; in other words, the force with which the fluid is discharged.
The higher the pressure, the greater the spraying powerI t is clear that a sprayer with good pressure, accompanied by a good telescopic pole, will be able to distribute the product to the highest points of the plant with very little effort and without the need to use a ladder.

Hose length

The length of the high-pressure hose supplied with the pump varies from 1.2 to 100 metres. A longer hose allows you to reach distant areas without having to move the pump, increasing work efficiency.

Engine brand

Engine type

• 4-stroke engines: these are petrol-powered and are quieter and more durable.
• 2-stroke engines: powered by a mixture of petrol and engine oil, they are lighter and more compact.

Nominal power

The nominal power of combustion pumps varies from 0.6 to 2.2 HP. This power is an indicative figure that refers to the power commercially attributed to the machine. The actual power, which is lower than the nominal power, is that measured at the crankshaft and is indicated by the manufacturer.

Battery type

Electric or battery-powered pumps can be equipped with different types of batteries.

• Lithium battery-powered: offer greater portability and durability.
• Lead-acid batteries: commonly used in cars, they are durable, reliable and economical.
• Some models can be used either manually or electrically with a battery.

Battery included or not

Some models of electric or battery-powered pumps include the battery with the purchase of the product, while in other cases the battery must be purchased separately.

Motor type

• Induction motors: also known as brushless motors, they are quieter and require less maintenance.
• Brush motors: these are more economical but require more maintenance.

Voltage (V)

The voltage of electric pumps measures the electrical voltage and ranges from 3 to 21 V. A higher voltage corresponds to a higher level of power output.

Amperes (Ah)

The electrical charge of battery-powered devices is expressed in Ah (ampere-hours) and ranges from 1.3 to 8 Ah. A higher capacity in Ah guarantees greater machine autonomy.

A spray pump is a device used mainly in agriculture for the uniform distribution of liquids on crops and plants. It is used for various purposes, including:

• Pesticide distribution: The pump allows pesticides to be applied to protect plants from insects and diseases.
• Foliar fertilisation: It is used to apply fertilisers directly to the leaves, improving nutrient absorption.
• Irrigation: It helps to irrigate plants and crops in a uniform and controlled manner.
• Preventive treatments: Used to distribute fungicides and other preventive solutions against diseases, pests and insects.

The main difference between an atomiser and a sprayer concerns the way they distribute the liquid and their specific use:

• Atomiser: Breaks the liquid down into very fine droplets, creating a mist that evenly covers the vegetation. Ideal for treating crops on tall drums and vineyards, where it is necessary to cover large areas that are difficult to reach. They often use a fan to push the mist deep into the plants.
• Sprayer: Dispenses the liquid in larger droplets through nozzles, ideal for targeted and concentrated applications. Perfect for low crops, gardens and small plantations, where precise coverage is required. Uses a pump to create pressure and push the liquid through the nozzles.

A backpack sprayer is a portable tool used to apply liquids and agricultural or fungicide treatments evenly over crops. Here's how to use it:

• Preparation: Fill the tank with the liquid to be distributed, which can be a pesticide, fertiliser or other treatment.
• Adjustment: Set the nozzles and fan to ensure optimal distribution of the liquid.
• Application: Wear the sprayer like a rucksack, switch it on and walk through the area to be treated, maintaining a steady movement to ensure even coverage.
• Maintenance: After use, thoroughly clean the tank and nozzles to prevent residue and blockages.

Sprayers are mainly used in agriculture and gardening to apply liquids such as:

• Pesticides and insecticides: Protect crops from insects and pests.
• Fertilisers: To provide essential nutrients directly to plants.
• Herbicides: To control the growth of weeds.
• Fungicides: Prevent and combat fungal diseases.

These devices allow for efficient and precise distribution of liquids, improving the effectiveness of treatments and reducing waste of resources.

An atomiser is a tool used mainly in agriculture to distribute liquids in the form of a fine mist. It is used for:

• Pesticide application: Protects crops from insects and diseases by distributing pesticides evenly.
• Foliar fertilisation: It provides nutrients directly to the leaves of plants, improving absorption.
• Fine irrigation: Distributes water in small droplets, useful for delicate crops.
• Phytosanitary treatments: Provides preventive or curative solutions against fungi and bacteria.

Atomisers are particularly useful for treating tall crops such as fruit trees and vineyards due to their ability to reach difficult areas.

A manual spray pump works by means of a pressure mechanism created by the user. Here are the steps for its operation:

• Filling the tank: Pour the desired liquid (e.g. pesticides, fertilisers) into the pump tank.
• Creating pressure: Operate the pump by hand, usually using a lever or piston, to create pressure inside the tank.
• Distributing the liquid: Use the lance connected to the tank to spray the liquid, adjusting the pressure and angle for optimal coverage.
• Maintenance: Clean the tank and nozzles after each use to prevent clogging and ensure efficient operation.

Electric spray pumps offer several advantages over manual models:

• Efficiency: The use of an electric motor reduces the physical effort required, allowing for faster and more consistent spraying.
• Precision: Adjustable settings allow for precise distribution of the liquid, improving the effectiveness of treatments.
• Versatility: They can be used for a wide range of applications, from small gardens to large crops.
• Ease of use: Simple to operate, they require less maintenance than petrol models.
• Eco-friendly: They do not produce harmful emissions, making them more environmentally sustainable.

Choosing a spray pump that suits your needs requires you to consider several factors:

• Type of crop: Consider the plants to be treated and their height to determine the type of pump (manual, electric, motorised).
• Area to be covered: Assess the size of the area to be treated in order to choose the tank capacity and pump flow rate.
• Type of liquid: Ensure that the pump is compatible with the type of liquid to be used (pesticides, fertilisers, herbicides).
• Ease of use: Opt for ergonomic models that are easy to handle, especially for prolonged use.
• Budget: Consider the quality-price ratio, taking into account initial costs and maintenance.

To ensure the proper functioning and longevity of a sprayer, it is essential to perform certain maintenance tasks on a regular basis:

• Cleaning: After each use, thoroughly clean the tank and nozzles to prevent residue and blockages.
• Nozzle check: Periodically check that the nozzles are not blocked and that they distribute the liquid evenly.
• Checking the seals: Check the seals and replace them if worn to prevent leaks.
• Lubrication: Lubricate moving parts, such as hand pumps, to ensure smooth operation.
• Hose inspection: Regularly check the hoses to ensure they are not damaged or worn, replacing them if necessary.
• Calibration: Calibrate the machine to ensure that the pressure and quantity of liquid distributed are correct.

Calibrating a sprayer is a crucial process to ensure that the liquid is distributed accurately and evenly. Here's what it involves:

• Pressure setting: Adjust the working pressure of the pump to achieve the correct droplet size and optimal coverage.
• Nozzle calibration: Ensure that all nozzles are calibrated to distribute the same volume of liquid. This includes checking the flow and replacing damaged nozzles.
• Checking the forward speed: Determine the forward speed of the operator or vehicle to ensure uniform coverage. This depends on the pump pressure and the type of nozzles used.
• Application volume control: Measure and adjust the volume of liquid distributed per hectare or square metre according to crop requirements and the specifications of the product used.
