This base-mounted end suction pump comprises a cast iron casing and a hydraulically balanced bronze impeller. The assembly utilizes a stainless steel shaft protected by a replaceable bronze shaft sleeve, which maintains the dry shaft design by isolating the shaft from the circulating fluid. A silicon-carbide seat and EPT rubber components construct the mechanical seal to support operation at 125 PSI. Integrally cast mounting feet on the casing provide support for the unit, while gauge ports are provided at the suction and discharge connections for pressure monitoring.
This 5 HP premium efficiency TEFC motor operates at 1750 RPM, incorporates Aegis grounding, and receives power from a 200-230V 3PH supply, achieving a DOE PEI rating of 0.44. 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.
