This base-mounted end suction pump comprises a cast iron casing and a bronze impeller. The assembly integrates a stainless steel shaft covered by a replaceable bronze shaft sleeve, utilizing a dry shaft design that maintains a 125 PSI pressure rating. A ceramic and EPT mechanical seal prevents fluid bypass within the casing. Centrally located discharge connections facilitate air venting, while gauge ports are provided on both suction and discharge lines to monitor system performance.
This 40 HP premium efficiency TEFC motor operates at 3450 RPM, incorporates Aegis grounding, and receives power via 380-460V / 3PH, resulting in 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 an electro-mechanical bypass, a main disconnect with 5kA SCCR, and holds an enclosure NEMA 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
