This base-mounted end suction pump comprises a class 30 cast iron casing with integrally cast mounting feet and a bronze impeller. The unit incorporates a dry shaft design that prevents fluid contact with the stainless steel shaft, which is covered by a replaceable bronze shaft sleeve. A ceramic and EPT mechanical seal allows for operation at pressures up to 125 PSI. The pump casing integrates suction and discharge gauge ports and a center-line discharge for positive air venting.
The 15 HP premium efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding for a 200-230V / 3PH power supply, yielding 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.
