This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The assembly utilizes a dry shaft design with a stainless steel shaft protected by a bronze shaft sleeve to isolate components from the circulating fluid. A mechanical seal incorporating ceramic seat halves and EPT rubber components facilitates operation at pressures up to 125 PSI without a wear ring. This pump includes gauge ports for suction and discharge connections to monitor system performance.
The pump operates with a 75 HP premium efficiency TEFC motor at 1750 RPM, which integrates Aegis grounding and utilizes a 380-460V / 3PH power supply, resulting in a DOE PEI rating of 0.46. The 'S' in the SCI 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
