This base-mounted end suction pump utilizes a cast iron casing and a bronze impeller to manage hydraulic flow. The assembly incorporates a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft and its replaceable stainless steel shaft sleeve. It integrates a mechanical seal constructed with a ceramic seat half and EPT rubber. This design maintains a 125 PSI pressure rating without a wear ring and includes suction and discharge pressure tappings for system monitoring.
The 40 HP premium efficiency ODP motor operates at 1750 RPM, incorporates Aegis grounding, and receives power via a 380-460V / 3PH supply with a DOE PEI 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.
