This end suction pump utilizes a cast iron casing with a center-line discharge for positive air venting and is constructed with a bronze impeller and bronze shaft sleeve mounted on a stainless steel shaft. Integrating a dry shaft design to protect against fluid contact, the assembly incorporates a mechanical seal with a ceramic seat and EPT rubber components. This pump is rated for a maximum pressure of 125 PSI without a wear ring.
Power is provided by a 5 HP Premium Efficiency TEFC motor operating at 3450 RPM, which integrates Aegis grounding and functions on a 200-240V / 1PH power supply with 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.
