This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. It incorporates a stainless steel shaft paired with a replaceable bronze shaft sleeve. The design utilizes a dry shaft configuration that prevents fluid contact with the shaft, rated for 125 PSI. A mechanical seal with a ceramic seat and EPT rubber components maintains internal pressure integrity. Pressure tappings are located on the suction and discharge connections to facilitate system monitoring, while the centerline discharge construction enables positive air venting.
The assembly utilizes a 50 HP Premium Efficiency TEFC motor operating at 3450 RPM with Aegis grounding, configured for a 380-460V 3PH power supply, resulting in a DOE PEI rating of 0.47. 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 holds an enclosure NEMA 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
