This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller to handle fluid transport. The assembly integrates a stainless steel shaft paired with a replaceable bronze shaft sleeve, utilizing a dry shaft design that prevents contact between the shaft and the circulating fluid. A mechanical seal with a ceramic seat and EPT rubber components maintains system integrity at pressures up to 125 PSI. This configuration allows for maintenance of the seal and internal components without disturbing the system piping.
Powered by a 20 HP premium efficiency TEFC motor operating at 1750 RPM, the assembly incorporates Aegis shaft grounding and operates on 230V 3PH power with 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 and holds an enclosure NEMA 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
