Essential equipment for operating a flexible tank.
A storage solution makes it possible to temporarily store a fluid, but it is not always enough to ensure its use in the field. To fill, drain, transfer, or distribute the stored liquid, integrating a motor pump unit quickly becomes essential.
Combined with a flexible tank, the motor pump unit transforms storage capacity into a truly operational solution. It ensures fluid circulation between the tank and its point of use : a vehicle, temporary installation, field service station, secondary depot, or mobile refuelling system.
In this type of configuration, motor pump units are more specifically associated with nitrile flexible tanks, particularly when dealing with fuels or technical fluids. Unlike PVC flexible tanks, which are more commonly used for certain water-related applications, nitrile tanks offer compatibility suited to hydrocarbons and demanding operating environments.
This combination is particularly well suited to fluid logistics operations, where rapid deployment, autonomy, and reliability are essential.
Make transfer, refuelling, and unloading easier.
The main role of a motor pump unit is to provide the flow rate and pressure required to move the fluid. It therefore makes it possible to control transfer, recovery, refuelling, or unloading operations, even in isolated or temporary environments.
Depending on requirements, it can be used for different types of fluids : drinking water, wastewater, diesel, petrol, kerosene, Jet A1, or AVGAS. This versatility makes it suitable for a wide range of civil, industrial, and logistics applications.
The motor pump unit therefore becomes the functional link between storage and the fluid’s final use. Without it, the tank remains a reserve. With it, it becomes a complete distribution and transfer solution.

A solution adapted to field constraints
Motor pump units can be configured according to the operating environment. They can be mounted on a skid, on a trailer, or integrated into a containerised solution. This modularity makes them easier to transport, install, and use on temporary or mobile sites.
This approach is particularly suited to the needs of sectors subject to strong operational constraints, such as defence, industry, mining, isolated worksites or temporary logistics operations. In these environments, the ability to store, transfer and quickly distribute a fluid directly impacts operational autonomy and efficiency.
The drive system can be thermal or electric, depending on the resources available and the constraints of the site. The choice between a positive displacement pump or a centrifugal pump also makes it possible to adapt the system to the fluid, the required flow rate, and the necessary pressure.
Flow rates can be adjusted according to the operations to be carried out, for example to supply a field station, ensure rapid refuelling, or organise a modular secondary depot. The aim is to provide a solution consistent with the stored volume, the transfer distance, and the conditions of use.
Accessories to complete the installation
Depending on the application, the motor pump unit can be combined with various accessories to make field operations easier. Hoses, couplings, hose reels, dispensing nozzles, flow meters, or filtration units can be added to complete the system.
For fuels, particularly in aviation, filtration and metering can play an important role in the distribution chain. These items enhance ergonomics, accuracy, and operational safety, without changing the motor pump unit’s main function: ensuring the transfer of the stored fluid.
Conclusion
The motor pump unit is a central component of a complete storage solution. It makes it possible to move from a simple fluid reserve to an operational system capable of transferring, distributing, refuelling, or unloading according to field constraints.
By integrating it with a flexible tank, Pronal offers a mobile, modular solution adapted to the needs of fluid logistics, whether for water, wastewater, or fuels.
