This base-mounted end suction pump is constructed with a cast iron casing and integrally cast mounting feet to support 125 PSI operation. The assembly integrates a bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve utilizing a dry shaft design to prevent circulating fluid contact. A mechanical seal comprising a ceramic seat and EPT rubber manages internal pressure. The unit design permits maintenance without disturbing connected system piping.
The 7.5 HP motor utilizes a Premium Efficiency design with a TEFC enclosure and operates at 3450 RPM, incorporating Aegis grounding within a 380-460V / 3PH power supply, yielding a DOE PEI rating of 0.47. 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 4X / IP 66 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
