This base-mounted end suction pump utilizes a cast iron casing and a bronze impeller to handle hydraulic loads. The assembly incorporates a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. Sealing is managed by a ceramic seat and EPT rubber mechanical seal arrangement. Rated for 125 PSI without a wear ring, the unit is constructed to facilitate maintenance of the internal components without disrupting existing system piping.
The system utilizes a 40 HP premium efficiency TEFC motor operating at 3450 RPM, integrated with Aegis grounding on a 380-460V 3PH power supply, 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.
