This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The assembly integrates a stainless steel shaft covered by a replaceable bronze shaft sleeve, utilizing a dry shaft design to prevent fluid contact. It utilizes a ceramic and EPT mechanical seal rated for 125 PSI. Gauging ports at both suction and discharge connections allow for monitoring system pressure. The unit incorporates a centerline discharge volute for air venting and includes integral mounting feet.
Powered by a 5 HP premium efficiency TEFC motor, this unit operates at 3450 RPM and incorporates Aegis grounding on a 380-460V / 3PH power supply, resulting in 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.
