This base-mounted end suction pump incorporates a cast iron casing and a bronze impeller. The design utilizes a dry shaft configuration with a stainless steel shaft and a replaceable bronze shaft sleeve, which prevents fluid contact with the shaft. A mechanical seal with EPT rubber and a ceramic seat half seals the assembly, operating at a pressure capacity of 125 PSI without a wear ring. This unit provides positive air venting through its centerline discharge and integrates integrally cast mounting feet for installation.
The assembly operates with a 1.5 HP, Premium Efficiency, TEFC, 1750 RPM motor equipped with Aegis Grounding, utilizing 200-230V / 3PH power supply, with a DOE PEI = 0.52. 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.
