This base-mounted end suction pump is constructed with a class 30 cast iron casing and a bronze impeller. The assembly utilizes a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. Mechanical sealing is achieved through a ceramic seat and EPT rubber components. This unit includes a wear ring and supports a pressure rating of 125 PSI.
Powered by a 3 HP Premium Efficiency TEFC motor operating at 1750 RPM with Aegis Grounding, the unit connects to a 200-230V 3PH power supply and maintains 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 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.
