This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and a bronze impeller dynamically balanced to ANSI Grade G6.3. The construction utilizes a dry shaft design that isolates the internal stainless steel shaft from circulating fluid, while a replaceable bronze shaft sleeve protects the shaft from wear. The mechanical seal assembly integrates a ceramic seat with EPT rubber components, maintaining a pressure rating of 125 PSI without a wear ring. This pump is engineered to allow service access to the bearing housing and mechanical seal without disturbing system piping connections.
The assembly utilizes a 25 HP premium efficiency TEFC motor operating at 1750 RPM, equipped with Aegis grounding and powered by a 380-460V / 3PH electrical supply, yielding a DOE PEI rating of 0.48. 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
