This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and a dynamically balanced bronze impeller. It integrates a stainless steel shaft covered by a replaceable bronze shaft sleeve, engineered with a dry shaft design that maintains a 125 PSI pressure rating. Fluid sealing consists of a ceramic seat and EPT rubber mechanical seal assembly. This construction allows service without disturbing system piping. The casing includes pressure tappings at the suction and discharge connections to facilitate system monitoring.
The 2 HP premium efficiency TEFC motor operates at 1750 RPM, integrates Aegis grounding, and utilizes a 200-230V 3PH supply, yielding a DOE PEI of 0.44. 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.
