This base-mounted end suction pump comprises a cast iron casing with a center-line discharge and a bronze impeller. The assembly utilizes a dry shaft design that prevents contact between the circulating fluid and the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. Mechanical sealing is provided by ceramic seat halves and EPT rubber, rated for operation up to 250°F. This unit accommodates a maximum pressure of 125 PSI without a wear ring.
The motor is a 1.5 HP premium efficiency TEFC model operating at 1750 RPM with Aegis grounding, configured for a 380-460V 3PH power supply, resulting in a DOE PEI of 0.44. 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.
