Storage tank 300 L, Dimm BOST-0020257

Storage tank 300 L

The storage tank 300 l DIMM reference BOST-0020257 (article code ART081576) is a pressure vessel / storage tank for water treatment with a useful capacity of 300 litres. Robust and durable, it is a key element of water treatment and distribution systems.

Design and materials

The tank is rotationally moulded in food-grade polyethylene (LDPE/HDPE), an inert material resistant to impact, UV and aggressive water. Its thick wall and optimised shape provide good mechanical strength once filled. Available in vertical (type CU) and horizontal (type CH) versions, it is easy to clean and taste-neutral.

Operation

The tank receives water by gravity or pump and returns it on demand. It creates a buffer reserve that secures supply during an outage, smooths consumption peaks and decouples production from draw-off.

Installation and connection

The 300 L tank is placed on a flat, load-bearing surface; the ports allow filling, draw-off and overflow. Its light weight makes handling and installation easy, indoors or outdoors (protected from frost).

Applications

Ideal for drinking water, borehole water, softened or reverse-osmosis water, booster installations, irrigation, livestock farming, industry and communities. The range covers domestic needs as well as large tertiary and agricultural volumes. In boosting, the tank stabilises pressure and protects the pump; in filtration, it houses the media or resin; in storage, it secures a water reserve. Each capacity in the range answers a precise use, from the small house to the farm building, and fits new installations as well as existing renovation projects with equal ease.

Maintenance and durability

A well-sized and correctly installed tank requires little maintenance. It is advisable to periodically check the pre-charge pressure (for bladder models), the tightness of the connections and the condition of the seals, and to drain or clean the vessel depending on use. Respecting the maximum working pressure and temperature guarantees a long service life. The wear parts (bladder, seals, strainers, valve) are available separately in the DIMM catalogue, which avoids replacing the whole tank and reduces the total cost of ownership over time. An annual check of the pressure, seals and connections is usually enough to maintain reliable and safe operation.

Good to know

The choice of volume depends on the pump flow, the number of simultaneous draw-offs and the desired comfort: a larger volume spaces out pump starts and extends its life. For aggressive or borehole water, favour composite or coated bodies. Outdoors, protect the tank from frost and direct UV. In case of doubt about sizing, the DIMM teams can advise on the capacity and accessories suited to your installation. A correct pre-charge pressure and a suitable volume also improve comfort, lower the pump's energy consumption and significantly extend the service life of the whole installation.
