This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. It incorporates a stainless steel shaft with a replaceable bronze shaft sleeve, utilizing a dry shaft design that prevents contact between the shaft and the circulating fluid. The unit integrates an EPT rubber and ceramic mechanical seal, providing a pressure rating of 125 PSI. This centrifugal pump design facilitates servicing without the removal of system piping, while the casing incorporates mounting feet and gauge ports at the suction and discharge connections.
The 50 HP motor utilizes a premium efficiency design with an ODP enclosure, operating at 1750 RPM. It incorporates Aegis grounding and operates on a 380-460V, 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
