This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The design integrates a dry shaft with a stainless steel shaft and a replaceable bronze shaft sleeve. This assembly utilizes a mechanical seal composed of a ceramic seat and EPT rubber, providing a pressure rating of 125 PSI without a wear ring.
This pump operates with a 25 HP premium efficiency ODP motor at 3450 RPM, utilizing Aegis grounding and a 380-460V 3PH power supply, resulting in 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
