This base-mounted end suction pump comprises a cast iron casing with a center-line discharge for positive air venting and a bronze impeller. The dry shaft assembly integrates a stainless steel shaft covered by a replaceable bronze shaft sleeve, which prevents contact between the circulating fluid and the internal shaft. A mechanical seal utilizing a ceramic seat and EPT rubber components facilitates operation at pressures up to 125 PSI without a wear ring. This pump is engineered to allow servicing without disturbing the system piping.
The 75 HP premium efficiency TEFC motor operates at 3450 RPM and incorporates Aegis grounding for power input via 380-460V / 3PH, maintaining a DOE PEI rating of 0.47. 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.
