This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and a bronze impeller. The construction utilizes a dry shaft design featuring a stainless steel shaft protected by a replaceable bronze shaft sleeve, which keeps circulating fluid from contacting the shaft. A mechanical seal with a ceramic seat and EPT rubber ensures fluid containment at a maximum pressure of 125 PSI.
The 20 HP, premium efficiency, TEFC motor operates at 3450 RPM and integrates Aegis grounding on a 380-460V, 3PH power supply, yielding 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.
