This base-mounted end suction pump integrates a cast iron casing with a bronze impeller and a stainless steel shaft. A bronze shaft sleeve protects the shaft in a dry design, preventing contact with the circulating fluid. The unit utilizes a mechanical seal comprising a ceramic seat half and EPT rubber. It operates at a maximum pressure of 125 PSI and does not include a wear ring.
The motor provides 30 HP with a Premium Efficiency rating in an ODP enclosure at 1750 RPM, and it incorporates Aegis Grounding for protection, powered by 380-460V / 3PH electricity, 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 an electro-mechanical bypass with a main disconnect and drive fusing, and holds an enclosure NEMA 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
