This end suction pump utilizes a cast iron casing with an integrally cast center-line discharge and mounting feet. The assembly incorporates a bronze impeller keyed to a stainless steel shaft, which includes a replaceable bronze shaft sleeve for protection against corrosion. A dry shaft design prevents contact between the circulating fluid and the shaft, maintaining an operating pressure capacity of 125 PSI. The mechanical seal consists of a ceramic seat with EPT rubber. Servicing of the bearing housing and mechanical seal occurs without removal of the system piping.
The 50 HP premium efficiency TEFC motor operates at 1750 RPM, incorporates Aegis grounding, and receives power from a 380-460V 3PH electrical supply, resulting in 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
