This base-mounted end suction pump comprises a class 30 cast iron casing and a bronze impeller. The pump utilizes a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft. A bronze shaft sleeve covers the shaft, and the mechanical seal consists of a ceramic seat and EPT rubber. The system handles pressures up to 125 PSI without a wear ring. This unit integrates a center-line discharge design to assist with air venting, and the bearing housing contains permanently lubricated ball bearings.
The 25 HP premium efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding for a 380-460V 3PH power supply. 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.
