This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The design integrates a stainless steel shaft with a bronze shaft sleeve to facilitate maintenance, while the dry shaft assembly prevents fluid contact with the shaft. It incorporates a wear ring and operates at a maximum pressure of 125 PSI. A mechanical seal utilizes a ceramic seat half and EPT rubber components to maintain system integrity.
This 50 HP premium efficiency TEFC motor operates at 1750 RPM and integrates Aegis grounding, a power supply of 380-460V / 3PH, and 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.
