This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The design integrates a replaceable bronze wear ring, while the assembly utilizes a stainless steel shaft protected by a bronze shaft sleeve. This unit utilizes a mechanical seal comprised of ceramic and EPT materials, providing a pressure rating of 125 PSI. Gauge ports are provided at suction and discharge connections for system monitoring.
The assembly utilizes a 15 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding, powered by a 208V / 3PH supply, resulting in 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 an electro-mech bypass with main disconnect and a 5kA SCCR rating and holds an enclosure NEMA 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
