Features and Benefits

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

Low operating risk

• Universal replacement seals, bearings, and motors available locally world-wide
• Optional isolated mechanical seal with sediment filters or separators for extended seal life in contaminated systems
• Vertical In-Line configuration allows for less disruptive pump service (casing stays in place)
