This base-mounted end suction pump incorporates a class 30 cast iron casing and a bronze impeller. The assembly utilizes a stainless steel shaft equipped with a replaceable bronze shaft sleeve, protecting the internal components through a dry shaft design. A mechanical seal composed of ceramic and EPT materials maintains pressure ratings up to 125 PSI. The unit integrates gauge ports at the suction and discharge connections to facilitate system monitoring.
The 40 HP premium efficiency ODP motor operates at 1750 RPM and utilizes Aegis grounding, powered by a 380-460V / 3PH electrical supply, with 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.
