This base-mounted end suction pump is constructed with a class 30 cast iron casing and an integrally cast mounting foot for center-line discharge. The hydraulic assembly incorporates a bronze impeller that is dynamically balanced to ANSI Grade G6.3. A stainless steel shaft protected by the manufacturer's dry shaft design prevents contact with circulating fluid and utilizes a replaceable bronze shaft sleeve. The mechanical seal consists of a ceramic seat half and EPT rubber, providing a temperature rating of 250°F. Operating at a pressure of 125 PSI without a wear ring, this pump is engineered with permanently lubricated, sealed-for-life ball bearings within a cast iron housing to maintain alignment.
This assembly utilizes a 75 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding, powered by a 380-460V 3PH electrical supply. 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.
