This end suction pump utilizes a cast iron casing and a bronze impeller to facilitate fluid movement. The internal construction integrates a stainless steel shaft paired with a replaceable bronze shaft sleeve to protect against fluid contact through a dry shaft design. A mechanical seal consisting of a ceramic seat half and EPT rubber components maintains hydraulic integrity. This assembly carries a 125 PSI pressure rating in configurations excluding a wear ring, while incorporating standard suction and discharge pressure tappings for system monitoring.
Powered by a 30 HP premium efficiency TEFC motor, the assembly operates at 1750 RPM with Aegis grounding and a 200-230V / 3PH power supply, yielding 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
