This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The assembly utilizes a stainless steel shaft covered by a bronze shaft sleeve, maintaining a dry shaft design rated for 125 PSI without a wear ring. A mechanical seal incorporating a ceramic seat and EPT rubber components isolates the fluid path. The design allows for servicing without disturbing the connected system piping, while the volute provides center-line discharge for air venting.
The 25 HP premium efficiency ODP motor operates at 1750 RPM and incorporates Aegis grounding, accepting a 200-230V 3PH power supply with a DOE PEI rating of 0.45. The 'S' in the SCI 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.
