This base-mounted end suction pump integrates a cast iron casing with a dynamically balanced bronze impeller. The design utilizes a stainless steel shaft protected by a replaceable bronze shaft sleeve in a dry shaft configuration, which facilitates operations up to 125 PSI without a wear ring. Mechanical sealing is managed by a ceramic seat with EPT elastomers rated for a maximum temperature of 250°F. The assembly incorporates flush seal line taps to assist in maintaining the integrity of the seal environment.
The motor provides 15 HP Premium Efficiency TEFC power at 3450 RPM, utilizing Aegis grounding for protection on a 380-460V / 3PH power supply, resulting in a DOE PEI of 0.45. 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.
