This base-mounted end suction pump is constructed with a class 30 cast iron casing and a stainless steel impeller. The assembly integrates a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. A ceramic and EPT mechanical seal regulates fluid containment within the pump volute. Rated for 125 PSI, the unit incorporates center-line discharge and integral mounting feet to facilitate installation.
This assembly operates on a 7.5 HP Premium Efficiency TEFC motor at 3450 RPM, utilizing Aegis grounding with a 380-460V / 3PH power supply, resulting in a DOE: PEI = 0.43. 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.
