This base-mounted end suction pump comprises a class 30 cast iron casing with integrally cast mounting feet and a 125 PSI rating including a replaceable wear ring. A bronze impeller balances the assembly, operating alongside a dry shaft construction that utilizes a stainless steel shaft covered by a replaceable bronze shaft sleeve to prevent fluid contact. The mechanical seal incorporates a ceramic seat half and EPT rubber, while the housing maintains a centered discharge orientation for positive air venting.
This assembly utilizes a 30 HP premium efficiency ODP motor operating at 1750 RPM with Aegis grounding on a 200-230V 3PH power supply, yielding 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.
