This base-mounted end suction pump integrates a cast iron casing and a bronze impeller within a dry shaft assembly. The design utilizes a stainless steel shaft and shaft sleeve, preventing contact between the fluid and the shaft. A mechanical seal comprising ceramic seat halves and EPT rubber seals the assembly, which is rated for 125 PSI and incorporates a wear ring.
The 75 HP premium efficiency TEFC motor operates at 1750 RPM, incorporates Aegis grounding, and receives power via 380-460V / 3PH supply, resulting in a DOE PEI rating of 0.46. 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.
