This base-mounted end suction pump utilizes a cast iron casing and a bronze impeller to facilitate fluid movement. The assembly integrates a stainless steel shaft paired with a bronze shaft sleeve, employing a dry shaft design rated for 125 PSI without a wear ring. A mechanical seal incorporating a ceramic seat half and EPT rubber maintains pressure integrity within the housing. The construction provides center-line discharge for positive air venting and includes pressure tappings on both the suction and discharge connections to allow for system monitoring.
The 25 HP Premium Efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding, powered by a 380-460V 3PH electrical supply, with 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 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
