This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The assembly integrates a stainless steel shaft paired with a replaceable bronze shaft sleeve and utilizes a ceramic mechanical seal with EPT rubber elements. Engineered with a dry shaft design, the pump prevents contact between the circulating fluid and the shaft, supporting operating pressures up to 125 PSI. Pressure tappings at the suction and discharge connections allow for monitoring, while the casing utilizes integrally cast mounting feet for installation.
Powered by a 5 HP premium efficiency TEFC motor, the assembly operates at 3450 RPM with Aegis shaft grounding on a 200-230V 3PH power supply, resulting in a DOE PEI rating of 0.49. 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.
