This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and a bronze impeller. The design integrates a dry shaft constructed of stainless steel protected by a replaceable bronze shaft sleeve. A ceramic mechanical seal with EPT rubber provides fluid containment, while the casing supports a maximum pressure rating of 125 PSI without a wear ring. This unit utilizes pressure tappings at the suction and discharge connections to facilitate system monitoring.
This assembly utilizes a 15 HP premium efficiency TEFC motor operating at 3450 RPM with Aegis grounding for use with 200-230V 3PH power, achieving a DOE PEI rating of 0.45. 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.
