This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The assembly utilizes a dry shaft design that protects the stainless steel shaft from contact with circulating fluid through the use of a replaceable bronze shaft sleeve. A mechanical seal, comprising an EPT rubber component and a ceramic seat, provides sealing at the shaft. The pump operates at a pressure rating of 125 PSI without a wear ring.
The pump utilizes a 25 HP premium efficiency ODP motor operating at 1750 RPM, equipped with Aegis grounding and powered by a 380-460V / 3PH supply, with 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.
