This base-mounted end suction pump integrates a cast iron casing with center-line discharge and integrally cast mounting feet for positive air venting. The unit incorporates a bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve, utilizing a dry shaft design rated for 125 PSI. A mechanical seal with a ceramic seat and EPT rubber ensures fluid containment during operation. Pressure tappings are provided on both the suction and discharge connections to allow for system monitoring, while the bearing housing contains permanently lubricated sealed-for-life ball bearings.
Powered by a 7.5 HP Premium Efficiency TEFC motor operating at 1750 RPM, the assembly includes Aegis grounding and utilizes a 200-230V, 3PH power supply, resulting in a DOE PEI rating of 0.46. 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.
