    HVAC-system pumping; light industrial/ process pumping (water or glycol based)

  • Description

    The Armstrong 4300 pipe-mounted pumps are designed for space-saving installation, high operating efficiency, and long service life

  • Configuration

    • Outside balanced or inside single spring mechanical seal • 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
