Armstrong 4600 Series Horizontal Split-Case Base-Mounted Pumps
Armstrong 4600 horizontal split-case (HSC) double suction pumps are base mounted and engineered to substantially reduce cost over rival designs across installation, operation, and lifetime maintenance. High-efficiency NEMA-premium motors ensure low energy consumption and cost. They are suitable for HVAC-system pumping, light industrial, and process pumping applications.
Armstrong 4600 pumps are equipped with high-efficiency NEMA-premium motors to reduce energy consumption and cost significantly. An ANSI/HI 1.3.5 rigid free-standing baseplate eliminates grouting, while a tilted-parting concept maximizes efficiency but minimizes inlet turbulence. All 4600 motors are suitable for inverter-fed service. 4600 pumps are low maintenance – leaking seals or noisy bearings can be serviced in minutes without disturbing other components, no lubrication or seal adjustments is required, and an integral bearing nut allows easy bearing removal and re-use. The unique cartridge design mechanical seal uses a standard replacement seal.
