This base-mounted end suction pump is constructed with a class 30 cast iron casing and a bronze impeller. The design incorporates a replaceable bronze wear ring and a dry shaft configuration that prevents circulating fluid from contacting the stainless steel shaft. A bronze shaft sleeve protects the shaft, while the mechanical seal utilizes ceramic and EPT materials. The volute includes a center-line discharge for air venting and provides pressure tappings for suction and discharge connections, with a maximum pressure rating of 125 PSI.
The 15 HP premium efficiency TEFC motor operates at 3450 RPM and integrates Aegis grounding on a 380-460V / 3PH power supply, with a DOE PEI rating of 0.47. 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 a NEMA 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
