This centrifugal end suction pump utilizes a cast iron casing with a center-line discharge. It integrates a bronze impeller balanced to ANSI Grade G6.3, mounted to a stainless steel shaft protected by a replaceable stainless steel shaft sleeve. This dry shaft construction prevents contact between the shaft and the circulating fluid. The assembly employs a mechanical seal containing a Ni-Resist seat half and EPT rubber, designed to operate at pressures up to 125 PSI without a wear ring.
The 25 HP Premium Efficiency TEFC motor operates at 1750 RPM, incorporates Aegis grounding, and receives power via 380-460V 3PH. 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
