Armstrong Series S & H in-line circulators are ideal for applications such as hydronic heating and cooling, domestic water systems, multi-stage zoning and general industrial service. Armstrong 3-piece circulators use a proven design that continues to evolve. The expanded temperature range makes them suitable for more applications, and the industry-accepted flange configuration makes s&h circulators a perfect solution when you need to change out pumps quickly without the need for pipe modifications.
