This end suction pump utilizes a cast iron casing with an integrally cast center-line discharge. The assembly incorporates a bronze impeller and a stainless steel shaft covered by a replaceable bronze shaft sleeve. A mechanical seal comprising ceramic seat halves and EPT rubber ensures fluid containment within the dry shaft design, which is rated for 125 PSI. This configuration allows for servicing of internal components without disturbing system piping.
The assembly integrates a 25 HP premium efficiency TEFC motor operating at 1750 RPM, equipped with Aegis grounding and powered by 380-460V 3PH electrical input, yielding a DOE PEI 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
