This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The design utilizes a dry shaft configuration that isolates the stainless steel shaft from the circulating fluid, aided by a replaceable bronze shaft sleeve. A mechanical seal consisting of ceramic and EPT materials manages fluid containment. The assembly is rated for 125 PSI without a wear ring and includes an integrally cast mounting foot. Suction and discharge connections possess pressure tappings for gauge monitoring.
The 7.5 HP premium efficiency motor utilizes Aegis grounding and operates at 1750 RPM on a 380-460V / 3PH power supply with 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.
