This base-mounted end suction pump comprises a cast iron casing with center-line discharge and a bronze impeller. The assembly integrates a stainless steel shaft protected by a replaceable bronze shaft sleeve, preventing contact with the circulating fluid. The mechanical seal assembly utilizes a ceramic seat with EPT components, rated for 125 PSI. Hydraulically balanced to ANSI Grade G6.3, the impeller operates within the casing, which incorporates gauge ports on both suction and discharge connections for pressure monitoring.
The 5 HP premium efficiency TEFC motor operates at 3450 RPM and incorporates Aegis grounding, utilizing a 380-460V, 3PH power supply with a DOE PEI rating of 0.49. 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.
