This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The assembly incorporates a stainless steel shaft paired with a replaceable bronze shaft sleeve, utilizing a dry shaft design to prevent circulating fluid contact. Mechanical sealing consists of a ceramic seat half and EPT rubber, providing a 125 PSI pressure rating with an integrated wear ring. The design allows for maintenance without disturbing system piping and includes provisions for gauge ports on both the suction and discharge connections.
The 5 HP premium efficiency TEFC motor operates at 1750 RPM and integrates Aegis grounding, utilizing a 380-460V / 3PH power supply, resulting in a DOE PEI 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.
