This base-mounted end suction pump utilizes a cast iron casing with a center-line discharge for positive air venting. The unit incorporates a bronze impeller and a stainless steel shaft covered by a replaceable bronze shaft sleeve. An EPT rubber and ceramic mechanical seal facilitates fluid isolation within the 125 PSI dry shaft design, which prevents contact between the shaft and the circulating fluid. This configuration allows maintenance on the mechanical seal and bearing housing without disrupting system piping connections.
The 5 HP premium efficiency ODP motor operates at 3450 RPM and integrates Aegis grounding with a 200-230V / 3PH power supply. 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.
