This base-mounted end suction pump incorporates a class 30 cast iron casing with integrally cast mounting feet and a bronze impeller dynamically balanced to ANSI Grade G6.3. The pump assembly utilizes a dry shaft design that isolates the shaft from the circulating fluid, further protected by a replaceable stainless steel shaft sleeve. Mechanical sealing is provided by a ceramic seat and EPT rubber components, capable of handling operating pressures up to 125 PSI. Both the suction and discharge connections include pressure tappings for system monitoring, while the bearing housing contains permanently lubricated, sealed-for-life ball bearings that are accessible for maintenance without disturbing the connected system piping.
The 20 HP premium efficiency motor is enclosed in a TEFC housing, operates at 1750 RPM, and incorporates Aegis grounding on a 380-460V, 3PH power supply, resulting in 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
