Industrial APT12 Diaphragm Well Tank 2 Gallon

American APT12 100 Diaphragm Well Tank, 2 Gallon (Model APTI-2 100) is a compact, pre-pressurized diaphragm storage tank designed for residential well systems. The 2-gallon unit uses a durable butyl rubber parabolic diaphragm to separate water from the pre-charged air, helping to smooth water delivery and reduce pump cycling. It features a lightweight steel shell, a powder-coated exterior with high UV resistance, and a fused water chamber with a powder-coated interior for longevity; the air valve is projection-welded for durability, and the water connection is located at the bottom and sized 3/4 in NPT. The tank has a maximum working pressure of 100 psi and is not ASME-certified, aligning with typical residential applications. According to its spec sheet, installation is suitable for both orientations, with dimensions of 13.75 inches in height and 8.5 inches in width, and a shipping weight of 5 pounds, making it a space-conscious choice for small-well setups.
