This base-mounted end suction pump utilizes a cast iron casing and a bronze impeller. The assembly incorporates a stainless steel shaft paired with a replaceable bronze shaft sleeve. This mechanical design employs a dry shaft configuration rated for 125 PSI, isolating the pump shaft from the circulating fluid. The unit utilizes a ceramic and EPT mechanical seal. Standard gauge ports located on the suction and discharge connections allow for pressure monitoring.
Powered by a 25 HP premium efficiency TEFC motor operating at 3450 RPM with Aegis grounding, this system operates on 380-460V / 3PH power with a DOE PEI 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.
