This base-mounted end suction pump comprises a class 30 cast iron casing and a bronze impeller. The design integrates a dry shaft with a replaceable bronze shaft sleeve and a stainless steel shaft, preventing contact between the circulating fluid and the shaft. A mechanical seal with a ceramic seat half and EPT rubber components maintains system integrity at a 125 PSI rating without a wear ring. This pump utilizes center-line discharge for air venting and includes gauge ports at the suction and discharge connections for pressure monitoring.
Powered by a 10 HP premium efficiency motor with a TEFC enclosure, the assembly operates at 3450 RPM and incorporates Aegis grounding on a 380-460V, 3PH power supply with a DOE PEI rating of 0.45. 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
