This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. It integrates a stainless steel shaft equipped with a replaceable bronze shaft sleeve and utilizes a dry shaft mechanical seal design with a ceramic seat and EPT rubber. This assembly maintains a pressure rating of 125 PSI without the use of a wear ring. Pressure tappings for gauge ports are provided on the suction and discharge connections. The pump incorporates flush seal line taps to facilitate the maintenance of the mechanical seal.
This 7.5 HP premium efficiency ODP motor operates at 1750 RPM and includes Aegis grounding, a 380-460V 3PH power supply, and a DOE PEI 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.
