This base-mounted end suction pump utilizes a class 30 cast iron casing and bronze impeller to facilitate fluid movement. The unit incorporates a dry shaft design that prevents fluid contact with the stainless steel shaft, which is protected by a replaceable bronze shaft sleeve. It includes a ceramic mechanical seal with EPT rubber elements, rated for 125 PSI. The design allows servicing without removing system piping, and the volute provides center-line discharge for positive air venting.
The assembly utilizes a 40 HP premium efficiency TEFC motor at 1750 RPM, integrating Aegis grounding and a 380-460V / 3PH power supply, yielding a DOE PEI of 0.44. The 'S' in the 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. No programming is included. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
