This end suction pump utilizes a cast iron casing and a bronze impeller to facilitate fluid movement. The assembly integrates a stainless steel shaft with a replaceable bronze shaft sleeve, employing a dry shaft design that prevents circulating fluid from contacting the internal shaft. A mechanical seal, constructed with a ceramic seat and EPT rubber, manages pressure containment for operations up to 125 PSI.
Powered by a 5 HP Premium Efficiency TEFC motor operating at 3450 RPM with Aegis grounding, the unit utilizes a 380-460V, 3PH power supply and maintains a DOE PEI rating of 0.47. 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.
