This base-mounted end suction pump is constructed with a class 30 cast iron casing and a bronze impeller. The assembly integrates a stainless steel shaft covered by a replaceable bronze shaft sleeve, utilizing a dry shaft design that prevents circulating fluid from contacting the shaft. The pump incorporates a mechanical seal comprising a ceramic seat half and EPT rubber. This configuration maintains a pressure rating of 125 PSI without a wear ring.
The 40 HP premium efficiency TEFC motor operates at 3450 RPM and integrates Aegis grounding, a power supply via 200-230V / 3PH, and a DOE PEI 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
