This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The design integrates a stainless steel shaft paired with a replaceable bronze shaft sleeve to maintain the dry shaft configuration, which prevents circulating fluid contact. The mechanical seal assembly consists of a tungsten carbide seat half and Viton rubber components. Rated for 125 PSI, the construction incorporates a wear ring. The pump casing serves as the structural foundation, utilizing integrally cast mounting feet for secure installation. Suction and discharge connections include pressure tappings for system monitoring, allowing for installation without disturbing system piping.
This pump operates with a 125 HP Premium Efficiency ODP motor at 1750 RPM, utilizing Aegis Grounding and a power supply of 380-460V / 3PH. 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.
