Flexible liquid storage The Wiefferink Flexitank (also known as Pillowbag internationally) is suitable for both temporary and permanent storage. The advantages of a flexible installation over a permanent structure makes the Flexitank ideal in countries where building permits or construction materials are difficult to acquire.  The Wiefferink Flexitank can be filled and emptied via leadthroughs. The product is ideal for connection to a filter system. The Flexitank concept is used in such places as Somalia, Pakistan and South Africa in this way, mainly in locations where drinking water cannot be offered in a regular manner.

High-grade, certified materials The Wiefferink Flexitank is manufactured for repeated use. We use highgrade materials that are extremely strong, light and flexible. These materials are thermally and high-frequency welded with care. The production method has been recorded in ISO documentation and certified by KIWA. Flexitank for fuels and other liquids Because the Flexitank can be made of special chosen flexible foil that is impermeable to a certain liquid, it can be used to store diesel, for example, or kerosene, de-icing fluid, liquid chemicals, fire-extinguishing water or wastewater. Easy to transport The small Flexitanks are extremely easy to transport in containers, pick-ups or flatbed trailers. Empty, the product takes up just 2% of its maximum volume. The Flexitank can be set up quickly and easily and it provides optimum protection for the liquid. This efficient liquid storage can be supplied in a variety of standard volumes (5, 10, 15, 20 and 25 m3) or in a custom size, up to 1500mÂł, entirely according to your specifications.
