This base-mounted end suction pump comprises a cast iron casing with center-line discharge and a bronze impeller. The assembly integrates a stainless steel shaft covered by a replaceable bronze shaft sleeve, utilizing a dry shaft design that prevents contact between the shaft and circulating fluid. A mechanical seal with silicon-carbide seat halves and EPT rubber components seals the assembly for operating pressures up to 125 PSI. This pump structure permits servicing of the mechanical seal and internal components without disturbing system piping connections.
Operating with a 30 HP premium efficiency TEFC motor at 3450 RPM, the assembly incorporates Aegis grounding and accepts a 200-230V 3PH power supply, resulting in 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.
