This base-mounted end suction pump incorporates a cast iron casing with center-line discharge and a bronze impeller. The assembly utilizes a dry shaft design to prevent contact between the circulating fluid and the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. A mechanical seal with a ceramic seat and EPT rubber ensures fluid containment. This pump maintains a pressure rating of 125 PSI without the use of a wear ring.
Powered by a 25 HP premium efficiency TEFC motor operating at 1750 RPM, the system includes Aegis grounding and utilizes a 380-460V 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
