This base-mounted end suction pump utilizes a class 30 cast iron casing with center-line discharge. The hydraulic assembly incorporates a bronze impeller keyed to a stainless steel shaft, protected by a replaceable bronze shaft sleeve that prevents fluid contact through a dry shaft design. A mechanical seal composed of a ceramic seat and EPT rubber components facilitates operation at pressures up to 125 PSI. This construction allows for maintenance without disturbing system piping.
The 25 HP premium efficiency TEFC motor operates at 1750 RPM, incorporates Aegis grounding, and utilizes 380-460V / 3PH power, resulting in a DOE PEI rating of 0.45. 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.
