This base-mounted end suction pump is constructed with a cast iron casing and integrally cast mounting feet. It utilizes a bronze impeller hydraulically balanced for system performance and a stainless steel shaft. The dry shaft design prevents contact between the circulating fluid and the shaft, which is protected by a replaceable bronze shaft sleeve. The mechanical seal assembly incorporates Ni-Resist seat halves and Buna rubber components, rated for a maximum pressure of 125 PSI with an included wear ring.
Operating with a 5 HP Premium Efficiency ODP motor at 1750 RPM, the assembly utilizes Aegis grounding and a 380-460V 3PH power supply, resulting in 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.
