This base-mounted end suction pump utilizes a center-line discharge cast iron casing with integral mounting feet to facilitate air venting. The assembly integrates a bronze impeller that is dynamically balanced and coupled to a stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. This dry shaft design prevents circulating fluid from contacting the shaft. The unit incorporates a mechanical seal with a ceramic seat and EPT elastomers, rated for 125 PSI operation. Pressure tappings are provided on both suction and discharge connections, and the bearing housing contains permanently lubricated sealed-for-life ball bearings.
This 1.5 HP premium efficiency ODP motor operates at 1750 RPM with Aegis shaft grounding and accepts 380-460V / 3PH power, resulting in a DOE PEI of 0.44. 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.
