The traditional sleeve bearing designs that are commonly used in this style of circulator require periodic oiling. The new Armstrong maintenance-free S & H Circulators eliminate the need for oiling, saving time and cost for building operators. The new MF S&H line will be offered as an additional option alongside the traditional sleeve bearing designs.
Armstrong Seal Bearing Assemblies are also compatible with many competing circulator models that require maintenance. This allows building owners to upgrade those installed circulators by replacing the SBA with the maintenance-free Armstrong versions.
The universal module that services the 2,3,4 and 5 Series S&H circulators is also compatible with installed SBAs. A wide range of large institutional customers, such as school boards, property management companies, and pump and motor service specialists will see significant benefits from this versatile service part.
