This base-mounted end suction pump comprises a class 30 cast iron casing with a center-line discharge for air venting. The assembly integrates a dynamically balanced bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve. Utilizing a dry shaft design, this unit prevents fluid contact with the shaft, while the mechanical seal incorporates a ceramic seat and EPT rubber. Gauge ports are provided at the suction and discharge connections for system monitoring, and the casing maintains a 125 PSI pressure capacity.
The 25 HP Premium Efficiency TEFC motor operates at 1750 RPM and integrates Aegis grounding on a 380-460V / 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 mechanical 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.
