This base-mounted end suction pump is constructed with a cast iron casing and incorporates an integrally cast mounting feet design. The internal hydraulic assembly comprises a bronze impeller and a stainless steel shaft protected by a bronze shaft sleeve. Utilizing a dry shaft design, the unit prevents circulating fluid from contacting the shaft during operation. The mechanical seal consists of an EPT rubber component paired with a ceramic seat half, supporting a pressure rating of 125 PSI in configurations without a wear ring.
Powered by a 5 HP premium efficiency ODP motor operating at 1750 RPM, the assembly incorporates Aegis shaft grounding and operates on 380-460V / 3PH power, achieving a DOE PEI rating of 0.47. 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.
