This base-mounted end suction pump utilizes a cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly incorporates a stainless steel shaft paired with a replaceable bronze shaft sleeve, isolated from circulating fluid through a dry shaft design rated for 125 PSI. A mechanical seal assembly consisting of a ceramic seat and EPT rubber components facilitates fluid containment. Pressure tappings are integrated into the suction and discharge connections for monitoring system performance, and the pump construction permits maintenance of the seal and internal components without disturbing the system piping.
This assembly utilizes a 75 HP premium efficiency TEFC motor operating at 3450 RPM with Aegis grounding, powered by a 380-460V / 3PH electrical supply, yielding 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.
