This base-mounted end suction pump utilizes a class 30 cast iron casing and a bronze impeller. The assembly incorporates a dry shaft design that prevents contact between the circulating fluid and the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. For fluid containment, the unit integrates a mechanical seal with a ceramic seat and EPT rubber, rated for 125 PSI. The volute provides center-line discharge for air venting and includes pressure tappings on both the suction and discharge connections.
A 20 HP premium efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding for the 200-230V / 3PH power supply, resulting in 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
