ELBI TOP-PRO®tector Series of Hydro-pneumatic water well tanks represent the latest development in well tank technology and come with a true deep-drawn design with one single body weld which gives it reliability, lightness and efficiency.
There are no inner domes to limit the diaphragms expansion, therefore, the maximum drawdown can be obtained in all conditions. Top-Pro®tector type tanks feature Elbi exclusive Top-Pro® internal coating. Top-Pro® coating is tested against ASTM standards for perfect adhesion.
|Diaphragm type design||Simple and reliable design.|
|Wide range of sizes available||From 2 to 119 gallons; we offer 10 different sizes to perfectly suit your application.|
|Heavy duty Butyl diaphragm||In house diaphragm manufacturing, using injection molding equipment, to ensure total control of this vital component. Proprietary food quality Butyl compound will not release taste or odor to water which makes it safe for alimentary applications. Solid construction, all diaphragms are QC inspected prior to assembly.|
|Exclusive TOP-PRO® corrosion proofing||Provides a high level of resistance against the corrosive action of water. *Completely phenol-free coating which satisfies government requirements for products designed to contain liquids for human consumption. Resistant to temperatures of up to 200°F.|
|Protection of water inlet||Plastic insert keeps the diaphragm safe, prevents well water debris from entering the tank.|
|Protected air valve||Recessed position prevents demage of the precharge air valve during shipping and handling. The plastic cap prevents accidental tampering.|
|Wide open steel base||Allows for an easy installation, does not limit tank position as in the case of closed based. Perfect for "T" installation in multiple tank set-up. The open style base provides better aeration, thus reducing condensation and premature rusting.*|
|Compact, light weight design||Space efficient design, replaces standard galvanized tanks up to three times as large; easy to handle and install.|
* When installed in normal environmental conditions. By normal environmental conditions its is meant environments which are free of acids, scale or chemical deposits or other factors known to affect paints, coatings and metals.
|Maximum Pump Flow (gpm)||System Pressure Ranges|
|Minimum Run Time in Minutes|
*DWT-50V and DWT-50H have the same drawdown
**DWT-25 and DWT-25H have the same drawdown
It is recommended that a periodic maintenance inspection of the complete system be performed by a professional licensed plumber. The inspection should be done at least once a year and during such check, the tank’s precharge should be tested and adjusted to the correct pressure if necessary. Failure to comply will void the warranty we strongly recommend the use of dielectric union when connecting dissimilar metals.
Elbi’s DWT series tanks are guaranteed to be free of workmanship or material defects for a period of 5 (five) years from the date of manufacturing. For a complete description of our warranty policy consult the literature which comes with the product or call our offices to request a copy.
