This end suction pump utilizes a cast iron casing with center-line discharge and integrally cast mounting feet to facilitate air venting. The unit incorporates a bronze impeller dynamically balanced to ANSI Grade G6.3, connected to a stainless steel shaft. A dry shaft design protects the internal components by preventing contact with the circulating fluid, while a replaceable bronze shaft sleeve assists in seal maintenance. The assembly integrates a mechanical seal composed of ceramic and EPT, rated for 250°F operation. Pressure tappings are located on both the suction and discharge connections to monitor performance, with the total construction rated for 125 PSI.
The motor provides 7.5 HP with premium efficiency, housed in an ODP enclosure at 1750 RPM, and integrates Aegis grounding on a 200-230V, 3PH power supply, resulting in a DOE PEI rating of 0.44. 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.
