    Up to 28,000 USgpm (1,800 L/s) flow; up to 500 ft (150 m) head

  • Temperature

    300oF (150oC)

  • Power Range

    1 hp to 1250 hp (0.75 kW to 900 kW)

  • Size

    1.5" to 20” (40 mm to 500 mm)

Low installed cost

  • 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
  • Isolated mechanical seal design with optional sediment filters or separators available to extend seal life in contaminated systems

Low energy consumption and operating cost

  • Armstrong 4300 pumps are available 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
  • Split-coupling allows replacement of mechanical seal without disturbing the pump or motor
  • No lubrication or seal adjustments required
