This end suction pump utilizes a cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly incorporates a dry shaft construction to prevent contact between the circulating fluid and the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. Mechanical sealing is provided by a ceramic seat with EPT rubber components. Pressure tappings are present on both the suction and discharge connections to facilitate system monitoring at 125 PSI.
The motor provides 1.5 HP, Premium Efficiency, TEFC enclosure, 1750 RPM, Aegis Grounding, 380-460V / 3PH power supply. The DOE PEI is 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.
