This base-mounted end suction pump utilizes a class 30 cast iron casing and a bronze impeller to facilitate fluid movement. The internal assembly incorporates a stainless steel shaft with a replaceable bronze shaft sleeve, protected by a dry shaft design that prevents circulating fluid from contacting the shaft. A mechanical seal with a ceramic seat and EPT rubber components maintains system integrity at pressures up to 125 PSI. The unit includes pressure tappings on the suction and discharge connections for monitoring and utilizes a bearing frame with sealed-for-life ball bearings.
Operating at 5 HP with a premium efficiency rating, the ODP motor runs at 1750 RPM and integrates Aegis grounding on a 200-230V 3PH power supply, achieving 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
