This base-mounted end suction pump is constructed with a cast iron casing and integrally cast mounting feet. The assembly incorporates a bronze impeller, a stainless steel shaft, and a replaceable bronze shaft sleeve utilizing a dry shaft design that prevents contact between the shaft and circulating fluid. A ceramic seat and EPT rubber mechanical seal provide sealing at the shaft interface. Rated for 125 PSI operation without a wear ring, the unit allows for maintenance of the seal and internal components without disturbing the system piping.
This assembly utilizes a 1.5 HP premium efficiency ODP motor operating at 1750 RPM with Aegis grounding, powered by 380-460V 3PH electricity, and achieving a DOE PEI of 0.44. 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.
