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, a 9-1/2" nominal diameter bronze impeller, and a bronze shaft sleeve. It utilizes a mechanical seal comprised of a ceramic seat, carbon rotor, and EPT rubber, rated for operation up to 250°F. The unit incorporates a dry shaft design to prevent contact with the circulating fluid and includes flush seal line taps along with pressure tappings on the suction and discharge connections.
The pump operates at 1750 RPM and is powered by a 10 HP WEG motor with a TEFC enclosure. It is configured for a 230-460V, 60Hz, 3PH power supply and uses a 215 JM frame with feet. The motor meets NEMA premium efficiency standards per MG1-12.55 and includes AEGIS shaft grounding. The assembly utilizes an across the line starting option and maintains a DOE PEI value of 0.9. The rear pullout design facilitates servicing without disturbing system piping, while the top center line discharge configuration reduces piping strain.
