This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The design integrates a dry shaft construction utilizing a stainless steel shaft paired with a replaceable bronze shaft sleeve to prevent fluid contact with the pump shaft. A mechanical seal with a ceramic seat and EPT rubber components seals the assembly, which is rated for 125 PSI. Hydraulically balanced to support parallel pumping and multi-pump control, the assembly utilizes a bronze impeller and provides gauge ports for suction and discharge connections.
Powered by a 20 HP premium efficiency TEFC motor, this assembly operates at 1750 RPM and incorporates Aegis grounding at a power supply of 380-460V and 3PH, achieving 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.
