This base-mounted end suction pump comprises a cast iron casing with an integrally cast mounting foot and a bronze impeller dynamically balanced to ANSI Grade G6.3. The dry shaft design utilizes a stainless steel shaft protected by a replaceable bronze shaft sleeve to isolate the internal shaft from circulating fluids. A mechanical seal constructed with a ceramic seat and EPT rubber ensures integrity during operation at pressures up to 125 PSI. Gauge ports for pressure monitoring and a drain port at the bottom of the casing are integrated into the pump housing to facilitate system maintenance.
The 25 HP premium efficiency ODP motor operates at 1750 RPM and incorporates Aegis grounding, power supply compatibility of 380-460V / 3PH, and a DOE PEI rating of 0.46. 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.
