This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The pump integrates a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. For pressure regulation, the assembly maintains a 125 PSI rating and utilizes a wear ring. The mechanical seal assembly consists of a ceramic seat and EPT rubber.
This unit operates at 40 HP, utilizes a premium efficiency motor with a TEFC enclosure, and spins at 1750 RPM. The motor integrates Aegis grounding and functions on 380-460V / 3PH power. 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.
