This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and a center-line discharge orientation for positive air venting. The unit integrates a bronze impeller and a stainless steel shaft equipped with a replaceable bronze shaft sleeve. This assembly utilizes a dry shaft design that prevents the circulating fluid from contacting the shaft and incorporates a silicon-carbide mechanical seal with EPT rubber. The internal construction supports a maximum operating pressure of 125 PSI without the use of a wear ring.
Driven by a 50 HP premium efficiency ODP motor operating at 1750 RPM, this pump integrates Aegis grounding on a 380-460V / 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.
