Armstrong close coupled vertical inline pumps are best suited for cooling and heating systems, pressure boosting systems, industrial applications that require a compact pump, and OEM (cooling tower, spray washer, fountain, etc.) applications.
The Armstrong 4300 series is compact but still delivers the reliability and flexibility you expect from Armstrong Pumps.
The Armstrong 4360 & 4380 pumps are available with standard NPT connections and ANSI 125 flanges, bronze impellers and standard JM/JP/56c motors with common electrical configurations. The wide array of connection sizes, impeller diameters and motors allows for a simple and direct replacement of almost any pump.
Armstrong’s close-coupled vertical in-line pump features economical inside-type, single-spring mechanical seal, serviced by removing the rotating assembly while the pump casing remains in the line. Dynamically balanced impeller assures smooth, vibration-free operation. Radially split volute with equal suction and discharge flange sizes. Separate tapped openings for gauge, flush and drain connections. Available in bronze fitted, all bronze, all iron, and ductile iron construction.
Armstrong’s economical, lower-range vertical inline pump for HVAC, domestic water systems, and industrial applications requiring a compact pump. Positive sealing assured by proven inside-type mechanical seal. Radially split volute permits removal of the motor and pump rotating assembly without removing the pump volute from the line. Fewer maintenance and servicing problems due to bearing-free pump design. Available in bronze fitted, all bronze, or all iron construction, in a range of sizes.
