This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and a bronze impeller. The design incorporates a stainless steel shaft protected by a replaceable bronze shaft sleeve and a dry shaft construction that isolates the shaft from circulating fluids. The pump utilizes a mechanical seal containing a ceramic seat and EPT rubber, maintaining a pressure rating of 125 PSI without a wear ring. Center-line discharge construction assists in positive air venting, while gauge ports are provided at the suction and discharge connections for monitoring system pressure.
The motor utilizes 20 HP, premium efficiency, TEFC enclosure, 1750 RPM, Aegis grounding, and 380-460V / three phase power supply with a DOE PEI rating of 0.46. 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.
