This base-mounted end suction pump comprises a class 30 cast iron casing with center-line discharge for positive air venting and an integrally cast bronze impeller. The pump utilizes a dry shaft design, which prevents circulating fluid from contacting the stainless steel shaft, further protected by a replaceable bronze shaft sleeve. A mechanical seal utilizes a ceramic seat and EPT rubber to handle internal pressures up to 125 PSI without a wear ring. This assembly incorporates pressure tappings on both the suction and discharge connections to facilitate system monitoring.
The assembly utilizes a 75 HP Premium Efficiency TEFC motor operating at 1750 RPM, equipped with Aegis grounding and powered by 380-460V / 3PH electrical supply, achieving a DOE PEI rating 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.
