This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. It incorporates a stainless steel shaft paired with a replaceable bronze shaft sleeve. The dry shaft design prevents the circulating fluid from contacting the shaft. The mechanical seal assembly utilizes a ceramic seat half and EPT rubber, providing a rating of 125 PSI without a wear ring.
Powered by a 25 HP premium efficiency TEFC motor operating at 1750 RPM, the assembly incorporates Aegis grounding and functions on 380-460V / 3PH power, achieving a DOE PEI of 0.44. 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 an electro-mechanical bypass, a main disconnect with 5kA SCCR, drive fusing, and a 2nd contactor, and holds an enclosure NEMA 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
