This end suction pump utilizes a class 30 cast iron casing with center-line discharge and integrally cast mounting feet for positive air venting. The bronze impeller is dynamically balanced to ANSI Grade G6.3 and attached to a stainless steel shaft. A dry shaft design prevents contact between the circulating fluid and the shaft, which is protected by a replaceable bronze shaft sleeve. Mechanical sealing is provided by a ceramic seat with EPT rubber, rated for 250°F. The construction assembly is supported by a structural steel base and maintains a pressure rating of 125 PSI without a wear ring.
3 HP Premium Efficiency motor with a TEFC enclosure operates at 1750 RPM and incorporates Aegis grounding on a 200-230V / 3PH power supply, resulting in a DOE PEI of 0.46. 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.
