This base-mounted end suction pump incorporates a cast iron casing with center-line discharge for positive air venting. The unit utilizes a bronze impeller and a stainless steel shaft with a replaceable bronze shaft sleeve. Engineered with a dry shaft design, the pump prevents circulating fluid from contacting the shaft. The mechanical seal integrates a ceramic seat half with EPT rubber, providing a pressure rating of 125 PSI. Permanently lubricated sealed-for-life ball bearings support the rotating assembly, while the casing provides gauge ports at the suction and discharge connections.
The 5 HP Premium Efficiency TEFC motor operates at 1750 RPM with Aegis grounding and accepts 380-460V / 3PH power, 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.
