This base-mounted end suction pump comprises a cast iron casing with a center-line discharge for air venting. The assembly integrates a bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve, which maintains a dry shaft design that prevents the circulating fluid from contacting the shaft. A mechanical seal utilizes a ceramic seat and EPT rubber to prevent leakage. This unit provides a pressure rating of 125 PSI without a wear ring.
This assembly utilizes a 10 HP premium efficiency TEFC motor operating at 3450 RPM, integrated with Aegis grounding and powered by a 380-460V 3PH supply, achieving a DOE PEI rating of 0.43. 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.
