This end suction pump utilizes a cast iron casing with integrally cast mounting feet and a bronze impeller. A stainless steel shaft protected by a dry shaft design and a replaceable bronze shaft sleeve ensures fluid isolation. The assembly incorporates a ceramic and EPT mechanical seal rated for 125 PSI. Gauging ports at suction and discharge connections allow for pressure monitoring, while the center-line discharge orientation facilitates air venting. The design permits servicing of the rotating assembly without disturbing the system piping.
The 15 HP Premium Efficiency TEFC motor operates at 3450 RPM, incorporates Aegis grounding, and supports a 380-460V / 3PH power supply, 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.
