This end suction pump integrates a class 30 cast iron casing with a center-line discharge and an integrally cast bronze impeller. It incorporates a dry shaft design that prevents circulating fluid from contacting the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. The mechanical seal utilizes an EPT rubber component and a ceramic seat, maintaining a pressure rating of 125 PSI in configurations without a wear ring.
Powered by a 5 HP Premium Efficiency ODP motor operating at 3450 RPM, the assembly utilizes Aegis Grounding and operates on a 380-460V / 3PH power supply with 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.
