This end suction pump is constructed with a cast iron casing and a bronze impeller. The assembly integrates a bronze shaft sleeve on a stainless steel shaft, utilizing a dry shaft design rated for 125 PSI. A mechanical seal with a ceramic seat and EPT rubber components isolates the fluid from the shaft. The unit is base-mounted and utilizes a center-line discharge for air venting.
The 7.5 HP motor employs premium efficiency construction and an ODP enclosure, operating at 1750 RPM with Aegis grounding and a 380-460V / 3PH power supply, resulting in a DOE PEI 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
