This base-mounted end suction pump comprises a cast iron casing with integrally cast mounting feet and a bronze impeller. The assembly utilizes a dry shaft design that incorporates a stainless steel shaft protected by a replaceable bronze shaft sleeve, preventing circulating fluid from contacting the shaft. Engineered with a mechanical seal using a ceramic seat half and EPT rubber, the unit handles pressures up to 125 PSI without a wear ring. Standard construction provides gauge ports at the suction and discharge connections, along with flush seal line taps to facilitate seal maintenance.
The 30 HP premium efficiency TEFC motor operates at 1750 RPM, integrates Aegis grounding, and accepts 380-460V three phase power, resulting in a DOE PEI 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.
