This base-mounted end suction pump incorporates a cast iron casing with an integrally cast mounting foot and a bronze impeller. The assembly utilizes a dry shaft design to isolate the stainless steel shaft from circulating fluid, aided by a replaceable bronze shaft sleeve. A mechanical seal with a ceramic seat and EPT rubber provides a fluid seal rated for 125 PSI. Center-line discharge ports permit positive air venting, while integrated taps accommodate pressure gauge or drain connections.
The 20 HP, Premium Efficiency, TEFC motor operates at 1750 RPM with Aegis Grounding at 380-460V / 3PH, maintaining a DOE PEI 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
