This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The design integrates a dry shaft with a bronze shaft sleeve and a stainless steel shaft, preventing contact between the shaft and the circulating fluid. A ceramic and EPT mechanical seal is utilized to maintain pressure integrity up to 125 PSI without a wear ring. The center-line discharge casing includes suction and discharge gauge ports to facilitate system monitoring.
The 40 HP Premium Efficiency TEFC motor operates at 3450 RPM and incorporates Aegis Grounding with a 380-460V / 3PH power supply, resulting in a DOE PEI of 0.46. The 'S' in the SFI 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.
