4300 VERTICAL INLINE PUMPS
- Applications
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
