This base-mounted end suction pump utilizes a class 30 cast iron casing with center-line discharge for air venting. The unit integrates a bronze impeller and a bronze shaft sleeve over a stainless steel shaft, which employs a dry shaft design to prevent contact between the circulating fluid and the shaft. A mechanical seal comprising a ceramic seat and EPT rubber seals the assembly. The pump is rated for 125 PSI operation without the use of a wear ring and includes suction and discharge pressure tappings.
This pump utilizes a 1.5 HP Premium Efficiency TEFC motor operating at 1750 RPM with Aegis grounding and a 200-240V 1PH power supply, yielding a DOE PEI rating 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 mechanical 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.
