This Taco CI Series close-coupled end suction pump features a 4" suction and 3" discharge with ANSI Class 125 flanges. The pump construction includes a cast iron casing, an 11" nominal diameter bronze impeller, and a bronze shaft sleeve. It utilizes a dry shaft design that prevents system fluid contact with the shaft. The mechanical seal consists of a ceramic seat, a carbon rotor, and EPT rubber, rated for temperatures up to 250°F. The rear pullout design permits maintenance without disconnecting system piping, and the top center line discharge allows for self-venting and reduced piping strain. Pressure tappings and flush seal line taps are provided on the casing.
The unit operates at 1750 RPM and is powered by a 15 HP WEG TEFC motor. The power configuration is 230-460V/60Hz/3PH with an across-the-line starting option. The motor is built on a 254 JM frame with feet and includes AEGIS shaft grounding. The motor meets NEMA premium efficiency standards per MG1-12.55. This pump assembly holds a DOE PEI rating of 0.91.
