This base-mounted end suction pump is constructed with a class 30 cast iron casing and a bronze impeller. The assembly incorporates a dry shaft design that utilizes a replaceable bronze shaft sleeve over a stainless steel shaft to prevent fluid contact. A mechanical seal consisting of ceramic and EPT components manages pressure ratings up to 125 PSI. Integrally cast mounting feet allow for secure installation on the provided base, while the center-line discharge configuration promotes positive air venting.
This 25 HP Premium Efficiency TEFC motor operates at 3450 RPM and integrates Aegis grounding on a 380-460V / 3PH power supply with 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.
