This base-mounted end suction pump utilizes a class 30 cast iron casing with an integrated center-line discharge for air venting. The internal assembly incorporates a hydraulically balanced bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve. This dry shaft design prevents circulating fluid contact with the shaft to mitigate corrosion risks. The mechanical seal utilizes a ceramic seat and EPT elastomer, rated for 125 PSI operation. Pressure tappings are located on the suction and discharge connections for monitoring system performance.
This assembly is powered by a 25 HP Premium Efficiency TEFC motor operating at 1750 RPM, which integrates Aegis Grounding for electrical protection. The motor supports 380-460V 3PH power, and the pump maintains a DOE PEI of 0.44. 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.
