LeapJet is a unique injection system for agricultural sprayers

For real-time and task map spray applications it is hard to predict the volume of crop protection you need. An injection system holds the crop protection liquids, therefore the main tank only contains water. The injection system injects the right dose.

LeapJet can inject from 12,5ml up to 12,5 liter per minute into the spraying system on-demand. The system calculated and injects autonomously the required volume. The flow range of the LeapJet enables spraying with 1 nozzle or 100 nozzles and/or from 10% to 100% application rate.

The LeapJet dosing pump is specially developed for precision spraying and it is chemical resistant. This pump can be connected to the machine’s spraying controller via CAN bus – making it possible for the control system to request the desired flow rate from the pump as the spraying conditions change. The pump’s design allows it to quickly converge on the new flow rate target. Dynamic spraying conditions do not influence the level of variation or precision.

Full Circulation System

To get the best spray quality an agricultural sprayer should be equipped with a full circulation system. A full circulation system enables you to spray directly without wasting water. Also while spraying, there are no dead ends in the system where you could get sediment issues, blocked nozzles, or contamination. Another major benefit of a good circulation system is that cleaning the spray lines or change to another application can be done fast, safe and with minimum time and water usage.

Injection and mixing

LeapJet can perfectly be combined with a circulation system. The injection takes place right before the pump, and the return from the circulation system is connected to the suction side of the pump to make a closed loop.

With injection before the spray pump, the pump is used as a mixing chamber. The pump is also used as a buffer, especially useful when spraying in very small quantities. For extremely small quantities, the LeapJet pump can run intermittently, keeping the concentration in the pump circuit at the correct level. When the rate increases, e.g. by opening more nozzles or increasing speed, the pump will run continuously again.

LeapJet primes the circulation system before spraying. The liquid in the circulation system will be circulated and at the same time, the crop protection agent(s) will be primed in 4 cycles to get the right concentration in the spray system.

You can start spraying at any time with the right concentration and mix. A tank agitation valve is still available to circulate through the tank if required.

The Technology Readiness Levels (TRLs)

LeapJet Injection System

BBLeap values open and transparent communication. This includes the stages of our technologies under development. To communicate our progress we use Technology Readiness Levels (TRLs). TRLs are developed and introduced by NASA in order to be consistent and uniform about communicating technology maturity. The LeapJet is identified to be currently in TRL 6. TRL 6 is described as “Subsystem(s) prototype(s) validated in relevant environment.

Frequently asked questions:

  • What is the primary purpose of the BBLeap LeapJet direct injection system?
    The BBLeap LeapJet direct injection system is designed to enhance precision and sustainability in agriculture by applying crop protection products exactly at plant level. This unique system eliminates residual liquid by injecting the required products on-demand into the spraying system, while the main tank only contains water. This allows farmers and contractors to work in real-time and using task maps with extreme accuracy, leading to more efficient use of resources and significantly more sustainable operations. The autonomous calculation and injection guarantee consistent quality and optimize every application.
  • How does the BBLeap LeapJet system contribute to better spray quality and efficiency?
    The BBLeap LeapJet system significantly increases spray quality and efficiency through its precise, on-demand injection capability. Combined with a full circulation system, this ensures direct spraying without waste and prevents sedimentation or blockages in the spray lines. Injection occurs before the spray pump, which also functions as a mixing chamber, guaranteeing a consistent concentration. This enables quick and safe changes in application, with minimal water usage and maximum control over the spraying process, resulting in optimal treatments at plant level.
  • What dosing capacities and flexibility does the BBLeap LeapJet injection system offer?
    The BBLeap LeapJet injection system offers an impressive injection range from 12.5 ml to 12.5 liters per minute, making it extremely flexible for various spraying applications. This autonomous system calculates and injects the required volumes precisely on demand. The wide flow range allows operation with one or one hundred nozzles, and application rates varying from 10% to 100%. The specially developed, chemical-resistant dosing pump also guarantees a rapid and accurate adjustment to changing spraying conditions, without loss of precision or variation in dosing.
  • What are the advantages of a direct injection system for crop protection?
    A direct injection system for crop protection offers crucial advantages for precision agriculture. It enables on-demand dosing, ensuring crop protection products are used only where and when needed. This leads to significantly less waste and targeted application at plant level. Since the products are stored separately from the water and mixed just before the nozzles, there is no residual liquid in the tank, which simplifies cleaning and increases safety. Furthermore, it allows for quick changes between different applications and maintains a constant concentration for reliable results.
  • How can advanced spraying technology contribute to more sustainable agricultural practices?
    Advanced spraying technology contributes significantly to more sustainable agricultural practices through extremely precise deployment of crop protection products. Systems that operate at plant level, such as direct injection systems, ensure that products are applied exclusively to the exact locations where they are needed and in the correct dosage. This minimizes total consumption, reduces the ecological footprint, and prevents unnecessary exposure of crops and the environment to chemicals. The result is more efficient cultivation while maintaining yield, healthier soil, and a reduced environmental impact, in line with a vision for 'Clean Food. Clean World.'.
