The American-Marsh product line during this era changed dramatically. New products introduced included the multi-stage split case product lines and the pre-ANSI heavy process end suction product lines. During the 1950's and 1960's, American-Marsh prospered by selling hundreds of models into the commercial, municipal and industrial markets.

The American-Marsh focus was lost for a short time during the 1970's and 1980's as the company stopped actively promoting it's products and services. This was corrected in the late 1990's as new management acquired the product line and changed the face of American-Marsh.
