This base-mounted end suction pump utilizes a cast iron casing and a bronze impeller to facilitate fluid movement. The design incorporates a stainless steel shaft paired with a replaceable bronze shaft sleeve and a dry shaft configuration that prevents fluid contact with the rotating assembly. A mechanical seal with a ceramic seat and EPT rubber ensures integrity during operation. This pump reaches a pressure rating of 125 PSI and does not include a wear ring.
The 20 HP Premium Efficiency TEFC motor operates at 1750 RPM with Aegis grounding and utilizes a 380-460V 3PH power supply, resulting in a DOE PEI rating of 0.45. 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.
