This base-mounted end suction pump utilizes a class 30 cast iron casing with integrally cast mounting feet and a center-line discharge orientation. The assembly integrates a bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve, adhering to a dry shaft design that prevents circulating fluid from contacting the internal shaft. Mechanical sealing consists of a ceramic seat with EPT rubber elements. Engineered for a maximum working pressure of 125 PSI, the casing incorporates a replaceable wear ring and suction and discharge gauge ports to facilitate system monitoring.
The 7.5 HP premium efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding, powered by a 200-230V 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.
