This base-mounted end suction pump utilizes a cast iron casing and a bronze impeller to move fluid. The unit incorporates a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft, which is covered by a replaceable bronze shaft sleeve. For sealing, the assembly integrates a ceramic seat with EPT components. The pump is rated for 125 PSI operation and includes 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, which integrates Aegis grounding and a 208V 3PH power supply, yielding a DOE PEI rating of 0.47. 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 an electro-mechanical bypass with a main disconnect and holds a NEMA 1 / IP 21 enclosure rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
