The pump is a \u003cstrong\u003e1\/25 HP\u003c\/strong\u003e unit that runs on \u003cstrong\u003e115 V, 60 Hz\u003c\/strong\u003e power, draws \u003cstrong\u003e0.74 A\u003c\/strong\u003e and turns at \u003cstrong\u003e3250 RPM\u003c\/strong\u003e. It is a small, quiet motor built to run for long stretches without much power draw, which is exactly what a boiler circulator is asked to do all heating season. If you are searching by the Taco number \u003cstrong\u003e007-F5\u003c\/strong\u003e or the Weil McLain number \u003cstrong\u003e511-405-113\u003c\/strong\u003e, this is the pump behind both.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003enameplate\u003c\/strong\u003e on this circulator is the information a tech wants in hand at the boiler. It is rated for \u003cstrong\u003e125 PSI\u003c\/strong\u003e maximum working pressure and \u003cstrong\u003e230°F (110°C)\u003c\/strong\u003e maximum water temperature, and it is \u003cstrong\u003eimpedance protected\u003c\/strong\u003e, \u003cstrong\u003econtinuous duty\u003c\/strong\u003e, enclosed to \u003cstrong\u003eType 2\u003c\/strong\u003e and wound with \u003cstrong\u003eClass H\u003c\/strong\u003e insulation. Impedance protection means the motor is designed so that a \u003cstrong\u003elocked rotor\u003c\/strong\u003e does not cook the windings, which is a welcome safety margin on a pump that lives in a hot mechanical room. Because the \u003cstrong\u003e007-F5\u003c\/strong\u003e is a \u003cstrong\u003ewet-rotor\u003c\/strong\u003e design, the \u003cstrong\u003erotor and bearings\u003c\/strong\u003e run in the system water, and that water lubricates and cools them. There is no mechanical \u003cstrong\u003eshaft seal\u003c\/strong\u003e to weep and no oil port to maintain, but it also means the pump must never be run dry. Purge the air out of the loop at startup and let the water do its job.\u003c\/p\u003e\n\n\u003cp\u003eWeil McLain addresses the interchange question directly in service bulletin \u003cstrong\u003eMB1907\u003c\/strong\u003e.
