This end suction pump is constructed with a cast iron casing and a bronze impeller. The design incorporates a dry shaft with a stainless steel shaft and a replaceable bronze shaft sleeve, preventing contact between the circulating fluid and the shaft. A mechanical seal utilizes a ceramic seat half with EPT rubber, providing a pressure rating of 125 PSI without a wear ring. This base-mounted unit integrates a bearing frame with sealed-for-life bearings. Gauge ports at the suction and discharge connections allow for monitoring of system pressure.
The 25 HP premium efficiency TEFC motor operates at 1750 RPM and incorporates Aegis grounding, powered by 380-460V 3PH electricity. 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.
