This base-mounted end suction pump comprises a cast iron casing with a center-line discharge design. The assembly utilizes a bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve, which prevents fluid contact with the shaft through a dry shaft design. This unit handles operating pressures up to 125 PSI and integrates a mechanical seal constructed with a ceramic seat and EPT rubber. The internal configuration permits maintenance of the rotating assembly and seal components without disturbing system piping connections.
The system utilizes a 1.5 HP premium efficiency TEFC motor operating at 1750 RPM, which integrates Aegis grounding and uses a 380-460V, 3PH power supply, resulting in a DOE PEI rating of 0.51. 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.
