Zilmet Hydro-Plus Pressure Tanks

Zilmet expansion vessels: the most reliable solution for all your needs.

Zilmet manufactures all of their own diaphragms, each carefully designed for the specific sized pressure tank to both extend the tank life and maximize drawdown. All diaphragms are manufactured with pure butyl and are all NSF61 Certified.
With our larger tank circumference and our industry leading thick diaphragms, Zilmet’s pressure tank diaphragms have an exceptionally long life.

Zilmet’s proprietary design for the underside of the diaphragm (TUV PSB approval according to SS375) forces water and sediment through the proprietary channels and grooves and up and out through the connector for a complete water exchange.
