This end suction pump incorporates a cast iron casing with a bronze impeller and a stainless steel shaft covered by a replaceable bronze shaft sleeve. The assembly utilizes a dry shaft design that maintains a 125 PSI rating and operates with a ceramic seat and EPT rubber mechanical seal. The construction allows for servicing without disturbing the system piping.
The 25 HP premium efficiency TEFC motor operates at 3450 RPM with Aegis grounding and accepts a 200-230V 3PH power supply, yielding a DOE PEI rating of 0.47. 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.
