This base-mounted end suction pump utilizes a cast iron casing with integrally cast mounting feet. The assembly incorporates a bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve. Engineered with a dry shaft mechanical design, the unit operates at a maximum pressure of 125 PSI. Sealing components consist of a ceramic seat and EPT rubber, providing a robust interface for fluid containment. Center-line discharge construction facilitates positive air venting, while gauge ports reside on both the suction and discharge connections to monitor system performance.
The motor provides 7.5 HP with premium efficiency, housed in a TEFC enclosure, operating at 1750 RPM with Aegis grounding, utilizing a 380-460V / 3PH power supply, and maintaining a DOE PEI rating of 0.48. 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.
