This base-mounted end suction pump is constructed with a cast iron casing and an integrally cast mounting feet design. The assembly incorporates a bronze impeller and a stainless steel shaft covered by a replaceable bronze shaft sleeve. This pump utilizes a dry shaft design that prevents circulating fluid from contacting the shaft and is sealed with a ceramic and EPT mechanical seal rated for 125 PSI operation. Pressure tappings are provided on both the suction and discharge connections for monitoring system performance.
This 20 HP premium efficiency TEFC motor operates at 1750 RPM, incorporates Aegis grounding, and receives power via a 380-460V 3PH supply, resulting in 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.
