This base-mounted end suction pump incorporates a cast iron casing with center-line discharge and a stainless steel NSF61 impeller. A dry shaft design prevents fluid contact with the stainless steel shaft, utilizing a replaceable bronze shaft sleeve. The mechanical seal consists of a ceramic seat and EPT rubber, rated for 125 PSI operation without a wear ring. This assembly allows for servicing without disturbing the system piping and integrates pressure tappings on both the suction and discharge connections.
The 7.5 HP premium efficiency TEFC motor operates at 3450 RPM with Aegis grounding, utilizes a 380-460V 3PH power supply, and maintains a DOE PEI of 0.49. 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.
