This base-mounted end suction pump comprises a cast iron casing with center-line discharge and an integrated replaceable wear ring rated for 125 PSI operation. The assembly integrates a stainless steel impeller and a stainless steel shaft protected by a dry shaft design, which incorporates a bronze shaft sleeve to isolate the shaft from the circulating fluid. Sealing is managed by a mechanical seal assembly utilizing a tungsten carbide seat paired with EPT rubber components. This construction provides structural stability for hydraulic performance, while pressure tappings on the suction and discharge connections allow for consistent system monitoring.
Powered by a 25 HP premium efficiency TEFC motor operating at 1750 RPM, the assembly utilizes Aegis grounding and accepts 380-460V 3PH power. 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.
