This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and a stainless steel impeller. The assembly integrates a dry shaft design with a stainless steel shaft covered by a replaceable bronze shaft sleeve to prevent fluid contact. This unit utilizes a mechanical seal constructed with a ceramic seat and EPT rubber, providing a 125 PSI pressure rating. Pressure tappings for suction and discharge connections are present, and the volute orientation allows for positive air venting.
The system utilizes a 50 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding, powered by a 380-460V 3PH supply, and achieves 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.
