Armstrong 4280 Commercial Pump

Armstrong 4280 commercial pumps are usually custom built for each application. This style pump is an end suction close coupled pump with the impeller attaching directly to the motor shaft. The pump will have a tag on a plate that will provide the model number, pump size, GPM, FTHD, impeller trim, motor horsepower and RPM as well as a serial number. This information is critical for identifying the correct parts.
