This base-mounted end suction pump incorporates a class 30 cast iron casing with a center-line discharge and integrally cast mounting feet. A bronze impeller, dynamically balanced to ANSI Grade G6.3, mounts to the shaft with a key and utilizes a dry shaft design to isolate the circulating fluid from the stainless steel shaft. This assembly integrates a replaceable bronze shaft sleeve and a mechanical seal composed of ceramic and EPT rubber, providing a 125 PSI rating without a wear ring. Pressure tappings are present at both the suction and discharge connections to facilitate system monitoring, while the bearing housing houses sealed-for-life ball bearings lubricated to meet a minimum L10 life of 60,000 hours.
Powered by a 10 HP premium efficiency TEFC motor operating at 3450 RPM, the assembly utilizes Aegis grounding and operates on 380-460V, 3PH power, achieving a DOE PEI rating of 0.47. 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.
