This base-mounted end suction pump utilizes a class 30 cast iron casing and a bronze impeller to facilitate fluid transfer. The assembly incorporates a dry shaft design that prevents contact between the circulating fluid and the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. For pressure containment, the unit integrates a mechanical seal constructed with a ceramic seat and EPT rubber, rated for 125 PSI operations. The pump casing includes integrally cast mounting feet and pressure tappings on both suction and discharge connections to allow for system monitoring.
The 7.5 HP premium efficiency TEFC motor operates at 1750 RPM and utilizes Aegis grounding on a 380-460V 3PH power supply, achieving 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 an electro-mechanical bypass, a main disconnect, and drive fusing, and it holds an enclosure NEMA 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
