This base-mounted end suction pump comprises a cast iron casing with a center-line discharge and integrally cast mounting feet. The assembly incorporates a bronze impeller and a stainless steel shaft, protected by a replaceable bronze shaft sleeve that maintains a dry shaft configuration. A ceramic and EPT mechanical seal rated for 125 PSI ensures fluid containment within the unit, while the casing design integrates gauge ports for monitoring suction and discharge pressures.
Powered by a 7.5 HP premium efficiency TEFC motor operating at 1750 RPM, the pump utilizes Aegis grounding on a 380-460V 3PH power supply, achieving a DOE PEI value of 0.44. 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.
