This base-mounted end suction pump is constructed with a class 30 cast iron casing and a bronze impeller. The design incorporates a dry shaft to prevent circulating fluid from contacting the stainless steel shaft, which is covered by a replaceable bronze shaft sleeve. A mechanical seal utilizes a ceramic seat and EPT rubber, providing a pressure rating of 125 PSI.
The motor provides 30 HP with premium efficiency and a TEFC enclosure, operating at 1750 RPM with Aegis grounding and a 380-460V / 3PH power supply, resulting in a DOE PEI rating of 0.48. 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.
