Product Overview

The polypropylene liner combined with an FDA approved high-grade butyl diaphragm makes up the wall chamber. This is held against the tank wall with a steel clench ring. The brass air valve, sealed by a threaded O-ring valve cap prevents air leaks. This range of tanks contains double diaphragms. The diaphragm is a chlorine-resistant 100% butyl type with a precision-moulded copolmer polypropylene liner for superior air and water separation. The diaphragm assembly is clenched together with a positive lock internal clench ring which contains drawdown water in a pre-charged air atmosphere, thus providing separation between the diaphragm and tank wall. This 'air buffer' means less problems with condensation. The air chamber is sealed with a fixed O-ring and closed cell foam
