This base-mounted end suction pump comprises a cast iron casing, a bronze impeller, and a bronze shaft sleeve on a stainless steel shaft. It incorporates a dry shaft design that eliminates contact between the circulating fluid and the shaft. The mechanical seal utilizes a ceramic seat half with EPT rubber and is rated for a maximum pressure of 125 PSI. This configuration allows for maintenance of the seal and the permanently lubricated sealed-for-life ball bearings without disturbing the system piping.
The assembly utilizes a 25 HP premium efficiency ODP motor operating at 1750 RPM with Aegis shaft grounding, 380-460V / 3PH power supply, and 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 an electro-mechanical bypass, a main disconnect with 5kA SCCR, and a NEMA Type 1 / IP 21 enclosure rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
