This base-mounted end suction pump comprises a cast iron casing with a center-line discharge and integrally cast mounting feet. The assembly utilizes a stainless steel impeller fitted to a stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. This mechanical design incorporates a dry shaft construction, ensuring the circulating fluid does not contact the shaft at pressures up to 125 PSI. A mechanical seal with a ceramic seat and EPT rubber components provides fluid containment during operation.
The 125 HP Premium Efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding for protection against electrical discharge, utilizing a 380-460V / 3PH power supply. 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
