This base-mounted end suction pump comprises a cast iron casing with a center-line discharge for positive air venting. The bronze impeller is dynamically balanced to ensure smooth rotation, while the dry shaft design integrates a stainless steel shaft protected by a replaceable bronze shaft sleeve to isolate the metal from the circulating fluid. The mechanical seal assembly utilizes EPT rubber and a ceramic seat, rated for 125 PSI. Integrally cast mounting feet on the casing provide structural support for the unit.
Powered by a 100 HP Premium Efficiency ODP motor operating at 1750 RPM, the assembly incorporates Aegis grounding and utilizes a 380-460V 3PH power supply, resulting in a DOE PEI 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 an electro-mechanical bypass, main disconnect, drive fusing, 5kA SCCR, and holds a NEMA Type 1 / IP 21 enclosure rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
