This base-mounted end suction pump comprises a cast iron casing with a bronze impeller and a bronze shaft sleeve installed over a stainless steel shaft. The dry shaft design prevents contact between the shaft and the circulating fluid, maintaining structural integrity at pressures up to 125 PSI. A mechanical seal utilizing a ceramic seat and EPT rubber manages fluid containment during operation. Center-line discharge construction allows for positive air venting, while integrally cast mounting feet provide support. The unit incorporates flush seal line taps to facilitate system maintenance and pressure tappings for monitoring suction and discharge connections.
This assembly utilizes a 20 HP Premium Efficiency TEFC motor operating at 1750 RPM with Aegis Grounding, energized by 380-460V 3PH power, providing 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
