ABSTRACT:
A flexible diaphragm/liner located in a tank connected to a liquid system. The bottom opening in the flexible diaphragm/liner is mounted in a hole in the bottom of the tank. The rigid tank is connected to a system to permit materials, like water, etc., to pass into and out of the interior of the flexible diaphragm/liner depending upon the operating needs of the system. The diaphragm/liner has an upper portion which is adapted to flex into or out of its lower portion in a predictable fashion, under pressure changes. A compressible gas is used in the upper portion of the tank.
