This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly utilizes a dry shaft design that prevents fluid contact with the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. For sealing, the pump incorporates a mechanical seal assembly consisting of a ceramic seat half and EPT rubber. The casing is rated for 125 PSI and integrates pressure tappings on the suction and discharge connections for system monitoring.
Powered by a 75 HP premium efficiency TEFC motor, the pump operates at 3450 RPM and integrates Aegis grounding on a 380-460V 3PH power supply with a DOE PEI rating of 0.47. 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
