This base-mounted end suction pump incorporates a cast iron casing with a center-line discharge and an integrally cast bronze impeller. The assembly utilizes a dry shaft design, which prevents contact between the circulating fluid and the stainless steel shaft. A replaceable bronze shaft sleeve protects the shaft, while a ceramic and EPT mechanical seal maintains the integrity of the housing. This unit is pressure rated to 125 PSI and includes a bronze wear ring to assist with long-term fluid handling.
Powered by a 25 HP, premium efficiency, ODP motor, the assembly operates at 1750 RPM and integrates Aegis grounding, a 380-460V / 3PH power supply, and has 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
