This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The design incorporates a dry shaft construction to prevent contact between the circulating fluid and the shaft, which consists of stainless steel protected by a bronze shaft sleeve. Rated for 125 PSI without a wear ring, the assembly utilizes a mechanical seal with a ceramic seat and EPT rubber. Gauge ports exist at the suction and discharge connections to facilitate system monitoring.
Powered by a 15 HP Premium Efficiency ODP motor with Aegis Grounding operating at 1750 RPM on 380-460V 3PH power, the unit maintains a DOE PEI of 0.47. 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.
