This base-mounted end suction pump integrates a cast iron casing with an integrally cast mounting foot and a bronze impeller. The design utilizes a dry shaft arrangement that protects the stainless steel shaft from fluid contact, supplemented by a replaceable bronze shaft sleeve. A mechanical seal constructed of ceramic and EPT components provides fluid containment, allowing for operation at a pressure of 125 PSI without a wear ring. This pump provides center-line discharge for air venting and includes suction and discharge gauge ports for system monitoring.
The 25 HP premium efficiency TEFC motor operates at 1750 RPM, incorporates Aegis grounding, and receives power via a 380-460V / 3PH supply, resulting in a DOE PEI 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.
