This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. It incorporates a stainless steel shaft paired with a bronze shaft sleeve to maintain the dry shaft design. The pump utilizes a mechanical seal composed of a ceramic seat and EPT rubber, rated for a pressure of 125 PSI without a wear ring. This unit allows serviceability without disconnecting system piping via its bearing housing configuration.
This assembly utilizes a 1.5 HP premium efficiency TEFC motor operating at 1750 RPM with Aegis grounding and 380-460V / 3PH power supply, resulting in a DOE PEI rating of 0.48. 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.
