This base-mounted end suction pump is constructed with a cast iron casing and utilizes a bronze impeller hydraulically balanced to ANSI Grade G6.3. The assembly integrates a dry shaft design that prevents contact between the circulating fluid and the shaft, which is comprised of stainless steel and covered by a replaceable bronze shaft sleeve. For pressure containment and seal performance, the pump is rated for 125 PSI and incorporates a ceramic seat and EPT elastomer mechanical seal. The casing includes center-line discharge for positive air venting and provides connections for gauge ports at the suction and discharge points.
Powered by a 5 HP premium efficiency TEFC motor operating at 1750 RPM, the assembly incorporates Aegis grounding and functions on 380-460V / 3PH power with 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
