This end suction pump utilizes a cast iron casing with a bronze impeller and a bronze shaft sleeve installed over a stainless steel shaft. The dry shaft construction prevents circulating fluid from contacting the shaft, which operates at a pressure rating of 125 PSI. A mechanical seal incorporating a ceramic seat and EPT rubber manages fluid containment within the housing. The assembly integrates suction and discharge connections for parallel pumping and multi-pump control, while the bronze impeller provides hydraulic balance to the system.
The assembly integrates a 15 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding and 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
