This base-mounted end suction pump incorporates a class 30 cast iron casing with center-line discharge and a 125 PSI pressure rating. It utilizes a bronze impeller and a bronze shaft sleeve over a stainless steel shaft, which is constructed using a dry shaft design to isolate the assembly from circulating fluid. The mechanical seal consists of an EPT rubber component with a ceramic seat half to manage fluid containment. Integrally cast mounting feet support the unit, which also includes a replaceable bronze wear ring to maintain hydraulic performance and a flush seal line for system maintenance.
This unit utilizes a 3 HP Premium Efficiency ODP motor operating at 1750 RPM with Aegis grounding and a 380-460V / 3PH power supply, resulting in a DOE PEI rating of 0.46. 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.
