This base-mounted end suction pump incorporates a cast iron casing with integrally cast mounting feet and center-line discharge for positive air venting. The rotating assembly utilizes a bronze impeller coupled to a stainless steel shaft that is protected by a replaceable bronze shaft sleeve. This dry shaft construction prevents circulating fluid contact with the shaft, while the mechanical seal utilizes ceramic and EPT components to maintain system integrity. The assembly is rated for 125 PSI operation without a wear ring.
The 1.5 HP premium efficiency TEFC motor operates at 1750 RPM and integrates Aegis grounding, power delivery of 380-460V / 3PH, and a DOE PEI rating of 0.51. 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.
