ARMSTRONG FLUID TECHNOLOGY Variable-speed fire pump
The Design Envelope Fire pump holds the distinction of being the first self-regulating variable-speed fire pump to meet NFPA-20 (2019 Edition), Section 4.8 standards, the company says. The product features increased design flexibility; increased reliability and safety supported by real-time and historic test and performance data; the ability to predict and report potential equipment failure that could result in expensive damage and/or loss of life; and a cost-savings of up to $1,500 per sprinkler branch, per floor, from the elimination of PRVs, the company notes.
