This base-mounted end suction pump utilizes a cast iron casing with center-line discharge for air venting. It integrates a bronze impeller keyed to a stainless steel shaft. A dry shaft design prevents circulating fluid from contacting the shaft, which is covered by a replaceable bronze sleeve. The mechanical seal assembly comprises ceramic and EPT materials rated for 250°F. Suction and discharge connections have standard pressure tappings, and the pump casing provides a 125 PSI rating.
The 25 HP Premium Efficiency ODP motor operates at 1750 RPM and incorporates Aegis grounding for use with 380-460V / 3PH power supplies, 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.
