This base-mounted end suction pump incorporates a cast iron casing with a bronze impeller. The design utilizes a dry shaft configuration with a stainless steel shaft and a replaceable bronze shaft sleeve. For fluid containment, a mechanical seal with a ceramic seat and EPT rubber components isolates the rotating assembly. Pressure tappings on the suction and discharge connections allow for monitoring through gauge ports. The pump assembly provides a maximum pressure rating of 125 PSI.
This assembly operates with a 7.5 HP Premium Efficiency ODP motor at 1750 RPM, incorporating Aegis grounding on a 200-230V / 3PH power supply, resulting in 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
