This base-mounted end suction pump utilizes a class 30 cast iron casing and a hydraulically balanced bronze impeller. The assembly integrates a stainless steel shaft protected by a replaceable bronze shaft sleeve, which prevents contact between the shaft and the circulating fluid. Fluid containment is managed by a mechanical seal composed of a ceramic seat and EPT rubber, rated for operation up to 125 PSI. This design allows for maintenance without disturbing system piping and incorporates a dry shaft construction.
This 40 HP Premium Efficiency TEFC motor operates at 3450 RPM and incorporates Aegis grounding for 200-230V 3PH power supply, resulting in a DOE PEI rating of 0.46. 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.
