This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. It integrates a stainless steel shaft covered by a bronze shaft sleeve, utilizing a dry shaft mechanical design rated for 125 PSI without a wear ring. The seal assembly comprises a ceramic seat half and EPT rubber for fluid containment. This pump incorporates a center-line discharge for positive air venting, allowing for maintenance without disrupting system piping.
Powered by a 5 HP Premium Efficiency TEFC motor operating at 1750 RPM with Aegis grounding, the assembly connects to a 380-460V, 3PH power supply and maintains 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
