This base-mounted end suction pump comprises a class 30 cast iron casing and a bronze impeller. The design utilizes a dry shaft arrangement with a stainless steel shaft and a replaceable bronze shaft sleeve to isolate the rotating element from the circulating fluid. A mechanical seal with a ceramic seat and EPT elastomer provides closure for the unit. The assembly maintains a pressure rating of 125 PSI and incorporates a wear ring to support hydraulic performance.
The motor is a 30 HP premium efficiency TEFC model operating at 1750 RPM, equipped with Aegis grounding and powered by a 380-460V, three-phase supply, with 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 and holds an enclosure NEMA 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
