This base-mounted end suction pump comprises a cast iron casing with center-line discharge and a bronze impeller. The assembly integrates a stainless steel shaft covered by a replaceable bronze shaft sleeve and a dry shaft design that prevents circulating fluid contact. A mechanical seal utilizes ceramic seat halves and EPT rubber to maintain system integrity. The unit supports an operating pressure of 125 PSI and incorporates a wear ring for improved hydraulic performance.
The 7.5 HP premium efficiency TEFC motor operates at 1750 RPM with Aegis grounding on a 200-230V 3PH power supply, resulting in a DOE PEI rating of 0.45. 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.
