Armstrong Fire Pumps
Design Envelope Fire Pump Unit
Fire Pumps
For More Information:
This product is designed, assembled, and tested to meet the Self-Regulating Variable Speed Fire Pump Unit, as described in NFPA 20 – 2019 Edition. A factory-built integrated fire pump unit consisting of pump, driver, and variable speed control unit, configured to maintain the set pressure until the maximum power draw is reached while acting as a variable speed pressure limiting control and/or a variable speed suction limiting control.
4700 Vertical Multistage Pumps
Fire Pumps

The Armstrong 4700 MultiStage Pumps are designed for reliability and low maintenance cost
Fireset End Suction Diesel & Electric
Fire Pumps
For More Information:
Armstrong Horizontal End-Suction (HES) fire pumps deploy a heavy-duty bearing frame to provide long and reliable service in an over-hung impeller design. The end-suction format eliminates the design layout constraints imposed by horizontal split-case pump configurations.
Fireset Horizontal Split Case Diesel & Electric
Fire Pumps
For More Information:
Armstrong Horizontal Split-case (HSC) fire pumps deploy a tilted parting design, with the casing of each pump split at a 15° angle. This maximizes efficiency by minimizing turbulence at the impeller eye. The angled split also keeps suction and discharge centerlines fully aligned – allowing for easy pre-piping on site.
Fireset Vertical In-Line
Fire Pumps
For More Information:
The Armstrong Vertical In-Line (VIL) fire pumps are ideal for applications where space is at a premium. The vertical in-line design saves up to 60% of floor space compared to equivalent horizontal split-case installations.
Fireset Vertical Turbine Diesel & Electric
Fire Pumps
For More Information:
The Armstrong vertical turbine (VT) fire pumps are the only pump type allowed to draw water from below-grade sources. Unlike centrifugal designs, vertical turbine fire pumps can be used with water supply levels that are below the pump suction. VT pumps don’t need priming as their impellers stay submerged in water at all times.
