This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The assembly utilizes a dry shaft design with a stainless steel shaft and shaft sleeve to prevent fluid contact. It incorporates a mechanical seal constructed with a ceramic seat and EPT rubber. This configuration supports pressure ratings of 125 PSI without a wear ring. The pump casing integrates a center-line discharge and mounting feet to facilitate installation.
The 7.5 HP premium efficiency TEFC motor operates at 1750 RPM, integrates Aegis grounding, and receives power via 380-460V / 3PH supply, achieving a DOE PEI 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 fused 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.
