This base-mounted end suction pump utilizes a cast iron casing with integrally cast mounting feet and a bronze impeller. The pump incorporates a dry shaft design that prevents contact between the circulating fluid and the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. A mechanical seal constructed with an EPT rubber component and a ceramic seat provides containment at 125 PSI. This assembly integrates a wear ring for extended service intervals, and the casing allows for positive air venting through its center-line discharge.
The 40 HP Premium Efficiency TEFC motor operates at 1750 RPM, integrates Aegis grounding, and accepts 380-460V three phase power with 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 an electro-mechanical bypass, main disconnect, 5kA SCCR, drive fusing, and a 3rd contactor, and holds an enclosure NEMA Type 3R / IP 64 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
