This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The assembly incorporates a dry shaft design that utilizes a stainless steel shaft paired with a replaceable bronze shaft sleeve to prevent fluid contact. A mechanical seal with a ceramic seat and EPT rubber manages sealing, rated for 250°F operation. Designed with a 125 PSI pressure rating, the casing includes an integrated wear ring. The center-line discharge arrangement facilitates air venting, while suction and discharge connections integrate pressure tappings for system monitoring.
A 5 HP Premium Efficiency TEFC motor at 3450 RPM with Aegis grounding operates on 380-460V / 3PH power, achieving a DOE PEI rating of 0.45. 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.
