This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The assembly utilizes a dry shaft design, which prevents fluid contact with the stainless steel shaft and stainless steel shaft sleeve. It integrates a mechanical seal with a ceramic seat and EPT rubber, rated for 125 PSI. A replaceable wear ring is included within the volute casing to maintain hydraulic performance.
The 5 HP premium efficiency TEFC motor operates at 1750 RPM with Aegis shaft grounding and a 380-460V 3PH power supply. 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.
