This base-mounted end suction pump comprises a cast iron casing with an integrally cast center-line discharge and a bronze impeller. The assembly integrates a stainless steel shaft covered by a replaceable bronze shaft sleeve and a dry shaft design that prevents circulating fluid from contacting the shaft. Mechanical sealing utilizes a ceramic seat and EPT rubber, sustaining pressures up to 125 PSI. Engineered for service without disturbing system piping, the construction incorporates gauge ports at both the suction and discharge connections for pressure monitoring.
Powered by a 40 HP Premium Efficiency ODP motor operating at 3450 RPM, this unit incorporates Aegis grounding and a 380-460V / 3PH power supply, achieving 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.
