This base-mounted end suction pump comprises a cast iron casing with a center-line discharge and a bronze impeller. It integrates a stainless steel shaft covered by a replaceable bronze shaft sleeve and utilizes a dry shaft design rated for 125 PSI without a wear ring. The sealing assembly incorporates a ceramic seat and EPT rubber to isolate the fluid. Integrally cast mounting feet facilitate installation, while the design allows for maintenance of internal components without disturbing the connected system piping.
The pump assembly utilizes a 7.5 HP premium efficiency ODP motor operating at 1750 RPM, incorporating Aegis grounding and powered by a 380-460V / 3PH electrical supply, with a DOE PEI rating 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.
