This base-mounted end suction pump comprises a cast iron casing with a center-line discharge and a bronze impeller. The assembly incorporates a dry shaft design that utilizes a stainless steel shaft covered by a replaceable bronze shaft sleeve, preventing contact between the circulating fluid and the shaft. A mechanical seal constructed with ceramic components and EPT rubber ensures fluid containment, with the unit rated for 125 PSI without a wear ring.
The motor provides 1.5 HP in a premium efficiency, TEFC enclosure operating at 1750 RPM, utilizing Aegis grounding and a 380-460V / 3PH power supply, resulting in a DOE PEI rating 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
