This base-mounted end suction pump incorporates a cast iron casing and a bronze impeller. It utilizes a stainless steel shaft paired with a bronze shaft sleeve to maintain structural integrity. The construction includes a dry shaft configuration that isolates the fluid from the shaft, while the mechanical seal assembly comprises a ceramic seat and EPT rubber. This pump assembly supports a maximum pressure rating of 125 PSI without the use of a wear ring.
The 20 HP premium efficiency ODP motor operates at 1750 RPM and incorporates Aegis grounding, drawing power from a 380-460V 3PH 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
