This base-mounted end suction pump is constructed with a cast iron casing and a stainless steel (NSF61) impeller. The assembly incorporates a dry shaft design that ensures the shaft remains isolated from circulating fluids, rated for 125 PSI without a wear ring. A stainless steel shaft is utilized, protected by a replaceable bronze shaft sleeve. For fluid containment, the pump integrates a mechanical seal comprising a ceramic seat half and EPT rubber.
The motor is a 1.5 HP premium efficiency TEFC model operating at 1750 RPM, which integrates Aegis grounding and functions on a 380-460V / 3PH power supply with a DOE PEI rating of 0.46. 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.
