This base-mounted end suction pump comprises a class 30 cast iron casing and a bronze impeller. A stainless steel shaft protected by a replaceable bronze shaft sleeve utilizes a dry shaft design to prevent contact with the circulating fluid. The unit is rated for 125 PSI and integrates a ceramic seat and EPT rubber mechanical seal capable of operating at temperatures up to 250 °F. Gauging ports at both suction and discharge connections allow for monitoring system pressure, while the casing supports positive air venting through its center-line discharge orientation.
This assembly utilizes a 3 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding on a 200-230V 3PH supply, achieving a DOE PEI rating of 0.5. The 'S' in the SFI 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.
