A smart molten metal pump system and method automatically controls the operating speed of the pump rather than requiring an operator to control the speed. The system includes a pump, a controller for controlling the speed of the pump and one or more vibration sensors (such as an accelerometer) to measure vibration. The controller receives input about the vibration of the pump or one or more pump components, and possibly other data, such as the temperature of the molten metal, and/or the depth of the molten metal, ad/or parameters related to the operation of the pump. The controller analyzes the one or more inputs to vary the speed of the pump, turn the pump off, and/or send a communication to an operator.

A system according to aspects of the invention includes a pump and a refractory casing that houses the pump or is in fluid communication with the pump. As the pump operates it moves molten metal upward through an uptake section of the casing until it reaches a rectangular outlet wherein it exits the vessel. The rectangular outlet is configured to be connected to, or may be attached to, a launder. Another system uses a wall to divide a cavity of the chamber into two portions. The wall has an opening and a pump pumps molten metal from a first portion into a second portion until the level in the second portion reaches an outlet and exits the vessel.

A method for delivering a flowable material into a mold or to infiltrate a preformed component, a fiber preform, or a green body includes: providing a crucible having a body configured as a reservoir to hold the flowable material; adding a metal, a metal alloy, or combination thereof into the body of the crucible, the metal or metal alloy having a predetermined melting point; heating the crucible with the metal or metal alloy contained therein to a temperature that is at or above the melting point of the metal or metal alloy; allowing the metal or metal alloy to melt to form the flowable material; and creating a siphon such that the molten metal or metal alloy flows from the body of the crucible to infiltrate the preformed component or to fill the mold.
