This base-mounted end suction pump incorporates a class 30 cast iron casing with integrally cast mounting feet and a replaceable bronze wear ring. The assembly integrates a dynamically balanced bronze impeller secured to a stainless steel shaft, which is encased in a bronze shaft sleeve. This dry shaft construction prevents contact between the circulating fluid and the shaft. The mechanical seal utilizes silicon-carbide seat halves and EPT rubber, providing a 125 PSI pressure rating. Gauge ports are located at the suction and discharge connections for pressure monitoring, while flush seal line taps allow for the connection of external filtration accessories.
The 3 HP premium efficiency TEFC motor operates at 1750 RPM, integrates Aegis grounding, and utilizes a 200-230V, 3PH power supply; the unit carries a DOE PEI 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.
