Thor is a small, efficient, low cost, nimble, high performance pump. There are many advancements that have been made to make the THOR pump a great performing pump.
¨ The pump has a 12" diameter rotor, which has the highest performance of any rotor that is on the market. ¨ The rotor has additional clearance between the diamond ground nitride bonded rotor bearing ring and the diamond ground nitride bonded base bearing ring. This reduces "sticking" ¨ The newly designed is very efficient. (The axial blade angle has been designed to push only the amount of flow into the casing that the radial blade angle can push out) The pump well is very quiet with very little movement. Thus very little dross formation in the pump well. The rotor is also more robust. Because of the newly designed rotor, the THOR pump has about a 25% higher flow rate for the same Rpm as the King Kong. ¨ The pump is also capable of producing a higher pressure. ¨ It is a three post model. The three posts are 5" diameter sleeved posts which are the same as the Monster posts. ¨ The base has a little "snout" which helps line the flow up in the arch. The front post is set back so that it has less chance to build up and fuse to the front wall. ¨ The shaft is a four-inch diameter sleeved shaft. It has a newly designed drive mechanism which makes it stronger and smoother running. ¨ The motor mount is redesigned. The coupling area is opened up for easier access. The coupling doors are larger and have chains so they won't get lost. ¨ The post clamps have "tops" so that the assembly of the pump is easier and the pump height is perfect every time. ¨ The base is designed different in that there is a uniquely designed chamber in the discharge area, which creates a vacuum. This reduces the back pressure and increases the flow. ¨ For gas injection pumps, the gas is injected and mixed with the molten aluminum in this vacuum. ¨ As the gas is pulled out of the pump outlet, it is aspirated into the metal.

Our Method
¨ Flow of metal is un-obstructed, passing debris without breaking the injection tube or foot. ¨ Newly designed base has a unique chamber in pump outlet that creates low pressure—pulling the gas into the metal.

Alternative Method Problems with angled tube method: ¨ Tube projects into the flow of metal and is broken by debris passing through the pump. ¨ Large bubbles form on down-stream side of the tube and can break away when the metal flow is low. ¨ Only the top stream of metal shears gas. This requires faster metal flow to shear gas since half of the flow is not shearing. ¨ Gas leakage occurs between tube and plug. ¨ Build up of mag-chloride occurs in exit and reduces flow
