This base-mounted end suction pump utilizes a class 30 cast iron casing with integrally cast mounting feet and a center-line discharge. The construction incorporates a bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve, which prevents fluid contact with the shaft. A ceramic and EPT mechanical seal seals the assembly, capable of 125 PSI pressure without a wear ring. This pump includes suction and discharge gauge ports along with a casing drain port.
A 25 HP premium efficiency TEFC motor operates at 3450 RPM, incorporates Aegis grounding, and runs on 380-460V 3PH power, 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
