This base-mounted end suction pump comprises a cast iron casing with center-line discharge and a bronze impeller dynamically balanced to ANSI Grade G6.3. The assembly integrates a dry shaft design that utilizes a stainless steel shaft covered by a replaceable bronze shaft sleeve, preventing contact between the circulating fluid and the shaft. A mechanical seal with a ceramic seat half and EPT rubber components provides a pressure rating of 125 PSI. Integrally cast mounting feet and pressure tappings on suction and discharge connections accommodate system maintenance, while a wear ring is included to sustain hydraulic performance.
The 20 HP premium efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding, powered by a 200-230V / 3PH electrical supply with 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.
