Armstrong Design Envelope pumps are a complete solution for heating and cooling systems. The integration of a perfectly matched pump, motor and intelligent variable speed drive creates an innovative high-value pumping solution.  The performance envelopes are mapped for the best pump efficiency at 50% of the design flow rate, where variable flow systems operate most often. This ensures a building’s hydronic pumping system consumes as little energy as possible. It also ensures that the installation meets ashrae 90.1 guidelines requiring 70% energy savings at 50% of peak load.

Fybroc® is the world leader in the design and manufacture of fiberglass reinforced pumps. These pumps are available in different materials to provide excellent corrosion resistance for tough applications including pumping of acids, brines, caustics, bleaches, solvents, seawater and a wide range of waste liquids.

Pumps can be vertical or horizontal flange mounted with 1750 RPM or 3500 RPM motors in single or three-phase. Pumps with low required NPSH for applications with minimal available NPSH to minimize effects of cavitations. Pumps typically bronze fitted with removable wear ring and impeller and equipped with industry standard motors that can be purchased locally. Suction strainers are not recommended on centrifugal pumps for these applications.


Pumps typically equipped with mechanical seals rated for temperatures up to 250°F; higher ratings standard on deaerator applications. Higher temperature seals and special faces available upon request.
