This base-mounted end suction pump comprises a cast iron casing with a bronze impeller and a stainless steel shaft. It incorporates a dry shaft design with a bronze shaft sleeve to isolate the shaft from the circulating fluid. The mechanical seal assembly consists of a ceramic seat and EPT rubber, rated for 250 °F. This unit is constructed for a maximum operating pressure of 125 PSI and utilizes center-line discharge for air venting. The design integrates integral mounting feet on the casing and includes a foot support at the driver end.
Operating with 7.5 HP, this Premium Efficiency ODP motor runs at 1750 RPM with Aegis grounding on a 380-460V / 3PH power supply, resulting in a DOE PEI of 0.44. 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.
