This centrifugal end suction pump comprises a cast iron casing and a bronze impeller. The assembly integrates a stainless steel shaft with a replaceable bronze shaft sleeve, utilizing a dry shaft design that prevents contact between the circulating fluid and the shaft. A ceramic and EPT mechanical seal regulates fluid containment within the pump. Rated for a maximum pressure of 125 PSI, the unit incorporates suction and discharge gauge ports to facilitate system monitoring.
The motor is a 7.5 HP premium efficiency TEFC model operating at 3450 RPM, utilizing Aegis grounding and powered by a 380-460V 3PH supply, with 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
