Armstrong Unveils New Tango Pump

Armstrong has introduced new, larger sizes of the Design Envelope Tango, a compact, low-carbon dual pump that ensures uninterrupted service, even during maintenance. The Design Envelope Tango includes two motors and two impeller assemblies in a single casing. Integrated valves can isolate one side of the pump for service, without interrupting flow or affecting occupant comfort.

New sizes are available with motors ranging from 15 to 40 horsepower and are capable of serving applications up to 2,000 GPM or 160 feet of pressure. Design Envelope Tango is a compact solution that reduces installation costs. Because the two rotating devices share a single casing, installation requires less piping. In addition, the vertical in-line orientation means the pump is installed in the piping and does not require an inertia base. The pumps are support by a cloud-based service that provides smart analytics, diagnostics and alerts to support HVAC system efficiency and extend product life.
