Many refractory products are custom-developed and manufactured for particular applications, and also usually contaminated with material they have absorbed while lining furnaces or ladles, which makes the recycling process a challenge.
The Q501 Series QuickPump shown here is configured with an air motor; an electric-motor option is available. The electric motor uses a 3-phase induction motor compatible with inverter-type motor speed controllers. The air-motor option has the benefit of operating without electricity and can be operated from bottled or house nitrogen.

Affordable Molten Metal Pump

Sept. 23, 2013
Small footprint, fits within crucibles Just 8 components, easy replacement Bottom-only feed or bottom-top feed

HIGH TEMPERATURE SYSTEMS INC. introduced the Q501 Series QuickPump, calling it “a pricing breakthrough for molten metal pumps.” “At 60% the cost of similar pumps, The Q501 Series is priced at 60% of the cost of similar pumps, and allows for manual or automated transfer of molten metal from furnaces and crucibles. It is designed to easily fit within small crucibles and holding furnaces with a base that measures less than 10.1x7.2 in. (26x19 cm) and weighs less than 70 lbs.

The Q501 Series QuickPump pricing breakthrough is the result of elegant design and streamlined manufacturing. The complete pump consists of only eight major components, of which only four components are exposed to the molten metal. All components of the pump are field-replaceable units and typical repair times are less than 15 minutes. All graphite components benefit from High Temperature Systems post-fabrication proprietary oxidation-resistant treatment to significantly extend the lifespan of the pump.

The Q501 Series QuickPump is available with either a bottom-only feed or bottom-top feed. When used to empty a furnace or crucible, the bottom-only feed configuration is most effective. When used for process transfer applications, the bottom-top feed draws equal portions of molten metal from above and below the pump base to improve homogeneity. The Q501 can be converted from a top-feed only to a bottom-top feed simply by swapping the impeller.

The Q501 Series QuickPump shown can be configured with an electric motor or an air motor. The electric motor uses a 3-phase induction motor compatible with inverter type motor speed controllers. The air motor option has the benefit of operating without electricity and can be operated from bottled or house nitrogen.

The Q501 Series QuickPump is ideal for transferring metal between furnace, transfer ladles, crucibles, and casting machines, thus eliminating the need for slower and more hazardous manual ladling or tapping out. The Q501 makes quick work of furnace pump-outs that are required for regular furnace maintenance and alloy changes. Also, it is ready for emergency situations that require emptying a furnace.

The Q501 Series QuickPump design is compatible with nonferrous metals including aluminum, zinc, and lead. An optional cover gas configuration extends the pump compatibility to include
