This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The design integrates a dry shaft system to prevent fluid contact, utilizing a stainless steel shaft with a bronze shaft sleeve. For fluid containment, it incorporates a ceramic and EPT mechanical seal rated for a maximum pressure of 125 PSI without a wear ring.
The pump assembly utilizes a 7.5 HP Premium Efficiency ODP motor operating at 1750 RPM, which integrates Aegis grounding and utilizes a 200-230V 3PH power supply, resulting in a DOE PEI 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
