This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The design integrates a stainless steel shaft covered by a replaceable bronze shaft sleeve, which prevents fluid contact with the shaft through a dry shaft construction. This unit handles pressures up to 125 PSI without a wear ring. The sealing system utilizes a mechanical seal constructed with a ceramic seat and EPT rubber components. The assembly allows for service access without disturbing system piping.
The pump utilizes a 40 HP premium efficiency TEFC motor operating at 3450 RPM with Aegis grounding, powered by 200-230V 3PH electrical input, yielding 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.
