This base-mounted end suction pump utilizes a center-line discharge design constructed of class 30 cast iron with integrally cast mounting feet. The assembly incorporates a bronze impeller and a stainless steel shaft covered by a replaceable bronze shaft sleeve, employing a dry shaft design that prevents circulating fluid from contacting the shaft. A mechanical seal with a ceramic seat and EPT rubber components maintains system integrity at pressures up to 125 PSI. This pump provides flush seal line taps to facilitate the protection of internal components, while suction and discharge connections integrate pressure tappings to monitor hydraulic performance.
Power is provided by a 50 HP premium efficiency TEFC motor operating at 1750 RPM, which integrates Aegis grounding and 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.
