This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The assembly integrates a stainless steel shaft protected by a replaceable bronze shaft sleeve, utilizing a dry shaft design that prevents circulating fluid from contacting the shaft. The mechanical seal incorporates a ceramic seat and EPT elastomer, supporting a pressure rating of 125 PSI without a wear ring. This unit utilizes center-line discharge for positive air venting and includes integrally cast mounting feet to provide structural stability.
The motor provides 7.5 HP at premium efficiency with a TEFC enclosure, operating at 1750 RPM and including Aegis grounding on a 380-460V, 3PH power supply with a DOE PEI rating of 0.44. 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.
