This base-mounted end suction pump comprises a class 30 cast iron casing and a bronze impeller. The assembly utilizes a dry shaft design with a stainless steel shaft covered by a replaceable bronze shaft sleeve to prevent fluid contact with the rotating shaft. A mechanical seal incorporating a ceramic seat and EPT rubber provides pressure containment up to 125 PSI.
The 75 HP premium efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding for protection against electrical discharge, powered by 380-460V / 3PH electrical input, yielding a DOE PEI of 0.46. The 'S' in the series denotes Taco's advanced Self-Sensing technology, which eliminates remote sensors and field wiring by using internal mathematical algorithms to calculate system resistance and automate variable flow. The included VFD is configured with a fused disconnect without bypass and holds an enclosure NEMA 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
