Expansion Tanks For Wells
We have a full line of well expansion tanks that are used anywhere from home to commercial applications. USA Roller Chain and Sprockets (USARC) is a direct authorized distributor for the globally renowned Zilmet Brand of tanks. We distribute Zilmet to our customers because they manufacture their own diaphragms that are carefully designed for the specific tank size, not only does this extend the life of the tank but it also maximizes drawdown. Something important to note is that all diaphragms are manufactured with pure butyl and are NSF61 Certified.
Because of the proprietary design by Zilmet the undersides of the diaphragm forces water and sediment through the proprietary channels and grooves and up and out the connector for a complete water exchange.
