This base-mounted end suction pump comprises a class 30 cast iron casing with a center-line discharge for air venting. The internal hydraulic assembly integrates a bronze impeller dynamically balanced to ANSI Grade G6.3. The pump utilizes a dry shaft design that prevents the circulating fluid from contacting the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. A ceramic and EPT mechanical seal rated for 250°F manages fluid containment. This assembly operates at a maximum pressure of 125 PSI and incorporates permanently lubricated, sealed-for-life ball bearings within the bearing housing.
This assembly utilizes a 2 HP Premium Efficiency TEFC motor operating at 1750 RPM with Aegis Grounding at 380-460V, 3PH, and maintains 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.
