This base-mounted end suction pump comprises a class 30 cast iron casing with integrally cast mounting feet and center-line discharge. It utilizes a bronze impeller dynamically balanced to ANSI Grade G6.3, connected to a stainless steel shaft covered by a replaceable bronze shaft sleeve. The dry shaft construction eliminates contact between the circulating fluid and the shaft. A mechanical seal consisting of ceramic seat and EPT rubber components provides fluid containment, allowing operation at a maximum pressure of 125 PSI without a wear ring.
The motor provides 3 HP with Premium Efficiency and an ODP enclosure, operating at 3450 RPM with Aegis Grounding for a 200-230V, 3PH power supply, yielding a DOE PEI of 0.49. 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.
