This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The design utilizes a dry shaft arrangement, which isolates the stainless steel shaft from the circulating fluid, further protected by a replaceable bronze shaft sleeve. A mechanical seal consisting of ceramic seat halves and EPT elastomer maintains pressure integrity up to 125 PSI. The assembly incorporates gauge ports at the suction and discharge connections for monitoring system performance and provides drainage via a bottom-casing port.
Powered by a 3 HP Premium Efficiency TEFC motor operating at 1750 RPM with Aegis Grounding, this pump utilizes a 200-230V 3PH power supply and holds a DOE PEI rating of 0.45. 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.
