This centrifugal end suction pump incorporates a class 30 cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly utilizes a dry shaft design that prevents contact between the circulating fluid and the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. This pump includes a mechanical seal comprised of a ceramic seat and EPT rubber, capable of operation at pressures up to 125 PSI. The discharge is center-line oriented to facilitate air venting, while the casing includes gauge ports at both the suction and discharge connections for system monitoring.
Powered by a 5 HP premium efficiency ODP motor, the assembly operates at 1750 RPM and integrates Aegis grounding on a 200-230V 3PH power supply, yielding a DOE PEI rating 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
