This base-mounted end suction pump integrates a cast iron casing and bronze impeller. The unit utilizes a stainless steel shaft protected by a replaceable bronze sleeve, maintaining a dry shaft configuration that prevents fluid contact with the internal shaft. A mechanical seal with a ceramic seat and EPT rubber manages pressures up to 125 PSI. The construction allows for servicing without disturbing system piping, and pressure tappings on the suction and discharge ports provide for fluid monitoring.
A 20 HP premium efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding, using 380-460V / 3PH 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 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.
