This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The design incorporates a stainless steel shaft paired with a replaceable bronze shaft sleeve and a dry shaft configuration that prevents fluid contact with the internal shaft assembly. Internal components utilize an EPT rubber and ceramic mechanical seal, and the unit is rated for 125 PSI operation. The casing integrates a wear ring to provide long-term serviceability and includes pressure tappings on both the suction and discharge connections for monitoring system performance.
Powered by a 75 HP premium efficiency ODP motor, this assembly operates at 1750 RPM, incorporates Aegis grounding, and accepts 380-460V / 3PH power input, resulting in 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
