This base-mounted end suction pump comprises a class 30 cast iron casing with a hydraulically balanced bronze impeller. Its dry shaft design utilizes a stainless steel shaft protected by a replaceable bronze shaft sleeve, preventing contact with the circulating fluid. The mechanical seal assembly incorporates a ceramic seat half with EPT rubber components, suitable for operations up to 125 PSI. This unit assembly includes a center-line discharge configuration to assist with positive air venting and provides access for maintenance without disturbing system piping.
The assembly utilizes a 30 HP premium efficiency TEFC motor operating at 3450 RPM with Aegis shaft grounding, rated for 380-460V / 3PH power supply, with a DOE PEI 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
