Transfer Pump Types
High Temperature Systems, Inc. has a three different transfer pump options:
Open-Style Pump - Supported by Posts
The open-style pump has an open, easy to access shaft, making the shaft easily accessed for cleaning and inspection.
While the assembly remains in the melt, you can remove the shaft and impeller by lifting them up from the pump assembly, easing shaft and impeller maintenance.
Closed-Style Pump - Enclosed Shaft Support
The close-style pump has an enclosed shaft that is housed in a protective refractory sleeve. While this prevents easy access for inspection and cleaning, the pump is optionally fitted with an inert gas feed that:
This pump can be fitted with an inert gas fitting to remove all oxygen present within the sleeve
Removing the oxygen eliminated oxide buildup at the metal level
Removing oxides will drastically improve lifetime of pump components
Cons: Requires a nitrogen/argon supply
Dual Position Pump - Enclose or Open Options
This pump would contain a transfer position as well as a circulation position
This would be useful for the alloying furnace to mix the aluminum into solution
We will have to discuss sizing and run some calculations to ensure that we can meet both circulation and transfer targets
