If your facility has three-phase electrical service, this is your entry point into the 10 HP tandem lineup — and at $5,660.75, it is $899 less than the single-phase equivalent (T10112HC1-S). Three-phase motors are more efficient, generate less heat, and provide smoother operation than single-phase motors of equivalent HP, which is why industrial facilities have historically run three-phase wherever possible.\u003c\/p\u003e\n\n\u003cp\u003eTwo cast iron pumps operate off a single motor, delivering the higher combined output and built-in redundancy of the tandem configuration without the added cost of a second motor setup.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e
