This base-mounted end suction pump is constructed with a class 30 cast iron casing and a bronze impeller. The assembly incorporates a dry shaft design that prevents contact between the circulating fluid and the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. This mechanical seal configuration utilizes a ceramic seat half with EPT rubber, rated for a maximum pressure of 125 PSI. The volute allows for center-line discharge for air venting and includes integrated gauge ports for suction and discharge connections.
The motor is a 75 HP premium efficiency TEFC model operating at 3450 RPM with Aegis grounding, configured for 380-460V / 3PH power, and carries a DOE PEI rating of 0.47. 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.
