This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. It integrates a stainless steel shaft paired with a bronze shaft sleeve, utilizing a dry shaft design that prevents circulating fluid contact. The mechanical seal assembly comprises ceramic seat halves and EPT rubber, rated for 125 PSI systems without a wear ring. Pressure tappings are positioned on both suction and discharge connections for monitoring.
Powered by a 60 HP premium efficiency TEFC motor, this assembly operates at 1750 RPM and incorporates Aegis grounding 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.
