This base-mounted end suction pump utilizes a class 30 cast iron casing and a bronze impeller to facilitate hydraulic performance. The dry shaft assembly comprises a stainless steel shaft covered by a replaceable bronze shaft sleeve, which prevents contact between the shaft and the circulating fluid. A ceramic mechanical seal with EPT rubber components handles system temperatures up to 250°F. The casing includes pressure tappings on the suction and discharge connections for monitoring, along with a drain port. This unit operates at a maximum pressure of 125 PSI without the use of a wear ring.
The 5 HP Premium Efficiency ODP motor operates at 1750 RPM and incorporates Aegis grounding, power delivery of 380-460V, 3PH, and a DOE PEI rating 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.
