Armstrong S&H 3-Piece Circulator Pumps

Armstrong S&H circulators include an ECM motor option and deploy a proven fixed-speed design, both cost-effective, durable, and easy to maintain. Models are available in the traditional sleeve-bearing design and the new, permanently-lubricated, maintenance-free design. They are suitable for HVAC systems and general-purpose applications.

Their proven seal design is made from strong, long-lasting materials for extended heavy-duty operation. Maintenance-free models eliminate periodic oiling. The S&H's three-piece modular construction uses a universal replacement shaft and bearing module, while the back pull-out design allows for easy replacement of wear components.
