Armstrong 4300-12x12x17 - Series 4300 Split-Coupled Vertical In-Line Pump, 12x12x17, 100 HP Motor

Optimized for high-capacity fluid circulation, the 4300-12x12x17 vertical in-line pump by Armstrong provides reliable performance in demanding commercial and industrial HVAC environments. This industrial-grade unit features a split-coupled design that simplifies maintenance while housing a high-efficiency 100 HP motor designed to handle large-scale hydronic requirements with precision.

The pump utilizes a vertical orientation to conserve valuable mechanical room floor space while maintaining high hydraulic efficiency. Its split-coupled construction allows for easy access to the mechanical seal and rotating assembly, enabling service without the need to remove the heavy motor or disconnect the piping from the main system lines.

Key System Performance Baselines:

• Motor Power: Robust 100 HP output for high-flow, high-head applications.
• Space Efficiency: Vertical in-line design minimizes total equipment footprint.
• Maintenance Accessibility: Split-coupled configuration streamlines seal and bearing replacement.
• Hydraulic Versatility: Engineered for sustained performance in closed-loop hydronic heating and cooling circuits.

⚠️ Application Profile: Ideal for large central plant chilled water loops, high-rise building secondary pumping, industrial process fluid circulation, and district heating/cooling systems requiring high head pressure and flow rate stability.
