This base-mounted end suction pump utilizes a class 30 cast iron casing with center-line discharge for positive air venting. The unit incorporates a bronze impeller dynamically balanced to ANSI Grade G6.3 and a stainless steel shaft. A replaceable bronze shaft sleeve protects the shaft within the dry shaft design, which prevents contact between the circulating fluid and the shaft. The mechanical seal consists of EPT rubber and a ceramic seat, rated for 125 PSI. Integrally cast mounting feet on the casing support the pump assembly.
The assembly operates with a 10 HP premium efficiency motor within an ODP enclosure at 1750 RPM, integrating Aegis grounding on a 380-460V 3PH power supply with a DOE PEI rating 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 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.
