ELBI TOP-PRO®tector Series of Hydro-pneumatic water well tanks represents the latest development in well tank technology and comes 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's exclusive Top-Pro® internal coating and are tested against ASTM standards for perfect adhesion.

Simple and reliable design.

From 2 to 132 gallons; we offer 11 different sizes to perfectly suit your application.

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.

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.

Plastic insert keeps the diaphragm safe, prevents well water debris from entering the tank.

Recessed position prevents demage of the precharge air valve during shipping and handling. The plastic cap prevents accidental tampering.

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.*

Space efficient design, replaces standard galvanized tanks up to three times as large; easy to handle and install.
