This base-mounted end suction pump comprises a class 30 cast iron casing with an integrally cast mounting foot and a dynamically balanced bronze impeller. Its dry shaft design utilizes a stainless steel shaft protected by a replaceable bronze shaft sleeve, ensuring the circulating fluid remains isolated from the shaft assembly. A mechanical seal incorporating a ceramic seat and EPT rubber handles temperatures up to 250°F. Rated for 125 PSI, the construction includes suction and discharge gauge ports alongside a casing drain port, facilitating maintenance without disrupting system piping.
This assembly utilizes a 20 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding on a 380-460V 3PH power supply, with a DOE PEI of 0.46. 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.
