This end suction pump utilizes a cast iron casing with center-line discharge and a bronze impeller. The design incorporates a dry shaft construction to prevent contact between the circulating fluid and the shaft, which consists of stainless steel protected by a replaceable bronze shaft sleeve. This assembly includes a mechanical seal comprised of a ceramic seat half and EPT rubber, rated for 125 PSI operation. The pump incorporates an internally balanced bronze impeller and supports service maintenance without the removal of system piping.
Powered by a 15 HP Premium Efficiency ODP motor operating at 1750 RPM, the assembly integrates Aegis grounding and functions on a 380-460V / 3PH power supply with a DOE PEI rating 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.
