This base-mounted end suction pump comprises a cast iron casing with center-line discharge for air venting and an integrally cast mounting base. The assembly utilizes a stainless steel impeller for hydraulic performance and a stainless steel shaft protected by a replaceable bronze shaft sleeve. This dry shaft design prevents contact between the circulating fluid and the shaft to mitigate corrosion. A mechanical seal with a ceramic seat and EPT rubber components maintains system integrity at pressure ratings up to 125 PSI.
The pump operates using a 5 HP Premium Efficiency TEFC motor at 1750 RPM, integrated with Aegis grounding and a 200-230V 3PH power supply, yielding 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.
