This base-mounted end suction pump comprises a class 30 cast iron casing and a bronze impeller. The assembly integrates a dry shaft design that eliminates contact between the fluid and the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. A mechanical seal utilizes a ceramic seat and EPT rubber, maintaining a pressure rating of 125 PSI without a wear ring. This configuration supports servicing without disturbing the system piping.
Powered by a 7.5 HP premium efficiency ODP motor operating at 1750 RPM, the assembly integrates Aegis grounding and accepts a 200-230V / 3PH power supply, resulting in a DOE PEI rating of 0.45. 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
