This base-mounted end suction pump comprises a cast iron casing with an integrally cast bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve. Engineered with a dry shaft design, the assembly prevents circulating fluid from contacting the shaft and utilizes a mechanical seal constructed with a ceramic seat and EPT rubber. This pump maintains a pressure rating of 125 PSI without a wear ring.
The motor is a 15 HP premium efficiency TEFC model operating at 3450 RPM with Aegis grounding and a 200-230V 3PH power supply, achieving 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
