This base-mounted end suction pump is constructed with a class 30 cast iron casing and an integrally cast mounting feet design to accommodate center-line discharge for air venting. The unit incorporates a bronze impeller and a stainless steel shaft covered by a replaceable bronze shaft sleeve. This assembly utilizes a dry shaft design to prevent circulating fluid from contacting the shaft and is equipped with a mechanical seal utilizing ceramic seat half and EPT rubber components. Rated for 125 PSI operation without a wear ring, the pump supports serviceability without the removal of system piping, while pressure tappings on the suction and discharge connections allow for gauge installation.
Powered by a 60 HP premium efficiency TEFC motor operating at 3450 RPM, the assembly incorporates Aegis grounding and functions on a 380-460V 3PH power supply with 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
