This base-mounted end suction pump comprises a class 30 cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly utilizes a dry shaft design with a stainless steel shaft covered by a replaceable bronze shaft sleeve to prevent fluid contact with the internal rotating components. A mechanical seal constructed with a ceramic seat half and EPT rubber seals the assembly, supporting operation at pressures up to 125 PSI. The design incorporates flush seal line taps and pressure tappings on both the suction and discharge connections to facilitate system monitoring and maintenance.
The 40 HP premium efficiency ODP motor operates at 3450 RPM and integrates Aegis grounding, power supply via 200-230V / 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.
