This close-coupled end suction pump incorporates a cast iron casing and a bronze impeller. The design utilizes a dry shaft configuration that protects the pump shaft from contact with the circulating fluid, while the internal assembly employs a bronze shaft sleeve. A mechanical seal is fitted with ceramic seat halves and EPT rubber components to provide sealing at pressures up to 125 PSI. Pressure tappings are integrated into both the suction and discharge connections to allow for system monitoring.
This assembly integrates a 25 HP Premium Efficiency TEFC motor operating at 3450 RPM with Aegis Grounding, utilizing a 380-460V 3PH power supply with a DOE PEI rating of 0.48. 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 an electro-mechanical bypass and a main fused disconnect with 100kA SCCR and holds an enclosure NEMA 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
