This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The assembly utilizes a stainless steel shaft paired with a bronze shaft sleeve, isolated by a dry shaft design that prevents contact between the circulating fluid and the shaft. A ceramic seat and EPT rubber mechanical seal maintain system integrity at pressures up to 125 PSI. The casing incorporates a replaceable wear ring to assist with maintenance.
This assembly operates with a 25 HP premium efficiency TEFC motor at 1750 RPM, which integrates Aegis grounding and functions on 380-460V / 3PH power with 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.
