This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly utilizes a dry shaft design, which prevents fluid contact with the stainless steel shaft. A bronze shaft sleeve covers the shaft, while a mechanical seal constructed with ceramic and EPT materials maintains pressure ratings up to 125 PSI. Gauge ports are provided at the suction and discharge connections to facilitate system monitoring.
A 50 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding connects to a 380-460V / 3PH power supply, 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.
