This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. It utilizes a stainless steel shaft with a replaceable bronze shaft sleeve, isolating the shaft from circulating fluid through a dry shaft design. A ceramic mechanical seal with EPT elastomers seals the unit, which operates at 125 PSI without a wear ring. Pressure tappings on suction and discharge connections allow for monitoring system performance.
The 2 HP premium efficiency TEFC motor operates at 1750 RPM, incorporates Aegis grounding, and accepts a 200-230V / 3PH power supply with a DOE PEI rating of 0.44. 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.
