This base-mounted end suction pump comprises a cast iron casing with an integrated wear ring and a stainless steel impeller. The unit incorporates a dry shaft design to prevent circulating fluid from contacting the stainless steel shaft. A bronze shaft sleeve protects the internal components, while the mechanical seal utilizes a ceramic seat and EPT rubber to maintain performance within a 125 PSI operating environment.
The assembly utilizes a 2 HP, premium efficiency, TEFC motor operating at 1750 RPM with Aegis grounding on a 380-460V / 3PH power supply, yielding a DOE PEI 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.
