This base-mounted end suction pump utilizes a cast iron casing with a bronze impeller and a stainless steel shaft. It incorporates a bronze shaft sleeve to protect the pump shaft from contact with the circulating fluid. The unit utilizes a mechanical seal constructed with a ceramic seat and EPT rubber. This design accommodates up to 125 PSI operation. Pressure tappings on suction and discharge connections are integrated for system monitoring.
The assembly utilizes a 7.5 HP Premium Efficiency TEFC motor operating at 1750 RPM, which integrates Aegis grounding and functions on a 200-230V 3PH power supply with a DOE PEI rating of 0.44. 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.
