This base-mounted end suction pump incorporates a class 30 cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly utilizes a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft and replaceable shaft sleeve, thereby minimizing corrosion. A mechanical seal composed of a ceramic seat and EPT rubber ensures fluid integrity under operating pressures up to 125 PSI. The pump includes a replaceable bronze wear ring to maintain hydraulic performance and provides gauge ports at the suction and discharge connections for system monitoring.
The assembly utilizes a 7.5 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis shaft grounding, configured for a 200-230V 3PH power supply, yielding 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
