This centrifugal end suction pump utilizes a cast iron casing with integrally cast mounting feet and a bronze impeller. The construction incorporates a dry shaft design that protects the stainless steel shaft from circulating fluid through a replaceable bronze shaft sleeve. For pressure containment, the unit is rated for 125 PSI. The mechanical seal assembly consists of a ceramic seat and EPT rubber components to manage system fluids. This assembly provides center-line discharge for positive air venting, and both the suction and discharge connections are tapped for gauge ports to monitor hydraulic operation.
The pump operates with a 7.5 HP premium efficiency TEFC motor at 3450 RPM, which integrates Aegis grounding for electrical protection. Power supply requirements consist of 200-230V and 3PH input, resulting in 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.
