Features
  • Vertical In-Line design eliminates the need for inertia bases, housekeeping pads, flex connectors, and field alignment or grouting requirements
  • Vertical In-line design minimizes space and pipe requirements
  • Design Envelope selections frequently recommend a smaller motor and/or pump which reduces installed cost
  • Armstrong 4380 pumps are equipped with high-efficiency NEMA-premium motors for significant reduction in energy consumption and cost 
  •  All motors are suitable for inverter-fed service 
  •  Vertical In-line design minimizes pipe requirements and related friction losses resulting in higher system efficiency
  • Universal replacement seals, bearings, and motors available locally world-wide
  • Vertical In-Line configuration allows less disruptive pump service (casing stays in place)
