This centrifugal end suction pump is constructed with a cast iron casing and a bronze impeller. The assembly incorporates a stainless steel shaft paired with a replaceable bronze shaft sleeve and a dry shaft mechanical seal design that prevents fluid contact with the shaft. This configuration supports pressure ratings up to 125 PSI without a wear ring. The seal assembly comprises a ceramic seat and EPT rubber components. The design includes integrally cast mounting feet and a centerline discharge for positive air venting, allowing for maintenance without disrupting system piping.
The 7.5 HP motor provides premium efficiency with an ODP enclosure. Operating at 1750 RPM, the motor incorporates Aegis grounding and utilizes a 380-460V, 3PH power supply, resulting in a DOE PEI rating of 0.46. 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
