This base-mounted end suction pump comprises a cast iron casing with a center-line discharge and a bronze impeller. The assembly integrates a stainless steel shaft protected by a replaceable bronze shaft sleeve, utilizing a dry shaft design that prevents the circulating fluid from contacting the shaft. An EPT ceramic mechanical seal manages fluid containment at the shaft interface. This pump construction supports a maximum operating pressure of 125 PSI without a wear ring and provides gauge ports at both the suction and discharge connections for system monitoring.
Powered by a 5 HP premium efficiency TEFC motor, this unit operates at 1750 RPM and integrates Aegis grounding, with a 200-230V 3PH power supply and a DOE PEI rating of 0.44. 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 mechanical disconnect without bypass and holds an enclosure NEMA 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
