This base-mounted end suction pump comprises a cast iron casing with center-line discharge and a bronze impeller. The assembly utilizes a stainless steel shaft protected by a replaceable bronze shaft sleeve and a dry shaft design, which prevents fluid contact with the shaft and accommodates pressures up to 125 PSI without a wear ring. A mechanical seal with a ceramic seat and EPT rubber components seals the assembly.
Powered by a 7.5 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding, the electrical system runs on 380-460V / 3PH power with a DOE PEI of 0.45. 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.
