This Taco CI Series close coupled end suction pump features a 4" suction and 3" discharge with ANSI Class 125 flanges. It utilizes an 11" nominal diameter bronze impeller and a cast iron casing with a bronze wear ring. The pump includes a dry shaft design with a replaceable slip-on bronze shaft sleeve that prevents fluid contact with the shaft. The mechanical seal is constructed with a silicon-carbide seat, a carbon rotor, and EPT rubber, supporting operation in clean water temperatures up to 250°F. This assembly also provides flush seal line taps and pressure tappings on the suction and discharge connections.
The pump is powered by a 20 HP Baldor motor with an ODP enclosure and AEGIS shaft grounding. It is configured for 230-460V, 60Hz, 3PH power and operates at 1750 RPM. The unit uses a 256 JM motor frame style with feet for mounting. This pump meets NEMA Premium Efficiency MG1-12.55 standards and has a PEI value of 0.91. The rear pullout design allows for servicing without disturbing system piping, while the top center line discharge configuration facilitates venting.
