This base-mounted end suction pump utilizes a cast iron casing with center-line discharge and integrally cast mounting feet. The hydraulic assembly integrates a bronze impeller and stainless steel shaft protected by a replaceable bronze shaft sleeve, preventing fluid contact with the shaft at a 125 PSI rating. A mechanical seal composed of a ceramic seat and EPT rubber accommodates fluid temperatures up to 250°F. Service to the bearing housing or shaft sleeve occurs without disturbing system piping.
Powered by a 7.5 HP Premium Efficiency TEFC motor, the pump operates at 3450 RPM, incorporates Aegis grounding, and accepts 200-230V / 3PH power, yielding a DOE PEI rating of 0.43. 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
