Made with the highest quality materials 

Our flexible pillow tanks used for liquid storage such as water storage, are made with the highest quality materials.

​The design and execution of the Flexicisternas are made with the help of automatic machines that join the material by termofusion. Our flexible pillow tanks for liquid storage are an excellent solution for different corporate areas.

All the Flexicisternas have a lateral tap where the outlet key is connected with a threaded terminal to adapt any kind of connection or element that may be required.

Equally, on the top area, it has an additional connection with a double threaded outlet, for the filling and vent, where we can adapt at the same time any kinds of compatible elements.

Thanks to these properties, Flexicisternas are the best solution for the storage of water and other effluents without requiring building works or additional costs resulting from the building and installation as well as any previous building permissions required.

Furthermore, they are an economical and advantageous investment for storage and water reserves, as it has no water losses due to evaporation, nor can it be polluted by outdoor elements, (eliminating therefore the appearance of algae), and it can also be used for the storage of slurry or effluents, avoiding therefore contamination from the outside, as well as the risk of substances falling inside or the direct contact with its contents.

  • Storage of liquid manures
