This base-mounted end suction pump comprises a class 30 cast iron casing with a center-line discharge for air venting. The unit incorporates a bronze impeller and a stainless steel shaft protected by a replaceable bronze shaft sleeve. This dry shaft configuration prevents circulating fluid from contacting the pump shaft. A mechanical seal with a ceramic seat and EPT rubber ensures system integrity, maintaining a pressure rating of 125 PSI without a wear ring. The bearing housing utilizes permanently lubricated, sealed-for-life ball bearings to support hydraulic operations.
The pump utilizes a 10 HP Premium Efficiency TEFC motor operating at 3450 RPM with Aegis Grounding on 380-460V / 3PH power, providing a DOE PEI of 0.45. 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.
