This end suction pump utilizes a cast iron casing with an integrally cast bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve. The dry shaft assembly prevents circulating fluid from contacting the shaft and incorporates a mechanical seal with a ceramic seat and EPT rubber. Engineered for systems with a 125 PSI operating capacity, the construction includes a wear ring for added durability and integrates flush seal line taps to facilitate maintenance.
The 40 HP premium efficiency ODP motor operates at 1750 RPM and incorporates Aegis grounding, power supply compatibility of 380-460V / 3PH, and 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 1 / IP 21 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
