This base-mounted end suction pump incorporates a cast iron casing and a bronze impeller. It utilizes a dry shaft design that prevents contact between the circulating fluid and the stainless steel shaft, which is protected by a bronze shaft sleeve. The pump integrates a mechanical seal with a ceramic seat half and EPT rubber, rated for 250°F. The casing includes suction and discharge pressure tappings and functions at 125 PSI without a wear ring.
Powered by a 5 HP Premium Efficiency ODP motor at 1750 RPM, the assembly integrates Aegis Grounding and 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 an electro-mechanical bypass, main disconnect with 5kA SCCR, drive fusing, and a third contactor, and holds an enclosure NEMA 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
