This base-mounted end suction pump is constructed with a cast iron casing and a bronze impeller. The assembly utilizes a stainless steel shaft covered by a replaceable bronze shaft sleeve, which prevents contact with circulating fluid through a dry shaft design. The mechanical seal consists of a ceramic seat and EPT rubber, rated for 125 PSI operation. This centrifugal pump includes integrally cast mounting feet for structural stability.
The system utilizes a 20 HP premium efficiency ODP motor operating at 1750 RPM, integrated with Aegis shaft grounding and a 380-460V / 3PH power supply, resulting in a DOE PEI 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 Type 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
