FireSet ES

  • Summary
  • Applications

    Fire-protection of buildings and other built infrastructure

  • Description

    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.

  • Materials

    Metal pump, frame, and components

  • Configuration

    Electric (50 Hz and 60 Hz) and diesel-driven designs. UL, ULC, and/or FM certified solutions available

  • Performance range

    250 – 1,750 USgpm

Low installation and service cost

  • Pump cost advantage over horizontal split-case design
  • Factory-based pump-motor alignment for easy installation
  • Back pull-out design for easy replacement of wear ring (no disruption of casing or piping) 
  • Advanced mechanical features including flexible pump-motor coupling (OSHA guard), self-venting centre line casing, and seal recirculation lines provide extended durability and easy maintenance 
  • Pump design using industry common parts (e.g. standard packing gland) and tools for easy and cost-effective maintenance 
  • Vertical discharge for maximum piping flexibility

Design Envelope

Lowest installed cost. Lowest operating cost.
