This base-mounted end suction pump utilizes a class 30 cast iron casing and a hydraulically balanced bronze impeller. The assembly incorporates a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft. A replaceable bronze shaft sleeve protects the shaft surface during operation. The mechanical seal assembly consists of a ceramic seat and EPT rubber components. The pump casing maintains a pressure rating of 125 PSI when operating without a wear ring.
The 5 HP premium efficiency TEFC motor operates at 3450 RPM and incorporates Aegis grounding on a 380-460V / 3PH power supply, resulting in a DOE PEI rating of 0.47. 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
