Our original concept of simplicity and quality is hand-built into every pump


A&F Machine Products Company has been a family-owned and operated corporation since 1964. The Helwig chemical feed pump had very meager beginnings. The founder of the company and designer of the original pump, Fred Helwig Sr, made a set of replacement check valves as a favor for a friend back in the 40's on a small lathe he had in his basement.
