Low Installation Cost Vertical Inline Centrifugal Pumps

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

Low installed cost:
a) Vertical In-line design eliminates the need for inertia bases, housekeeping pads, flex connectors, and field alignment or grouting requirements
b) Vertical In-line design minimizes space and pipe requirements
c) Isolated mechanical seal design with optional sediment filters or separators available to extend seal life in contaminated systems

Low energy consumption and operating cost:
a) Armstrong 4300 pumps are available with high-efficiency NEMA-premium motors for significant reduction in energy consumption and cost.
b) All motors are suitable for inverter-fed service.
c) Vertical In-line design minimizes pipe requirements and related friction losses resulting in higher system efficiency.
d) Split-coupling allows replacement of mechanical seal without disturbing the pump or motor.
e) No lubrication or seal adjustments required
