Pump Installation Planning Guidelines – Part 2 – Pump Startup Scheduling

Overview In Part 1 we discussed the pump installation planning from the highest level. We identified the typical stakeholders, and we briefly touched on each stakeholders concerns and goals. The project’s overall schedule is scalable and is highly dependent upon the size of the operation, the number of furnaces, and the role the furnaces play …


Air Supply Considerations for an Air Motor on a Molten Metal Pump

Our pumps are offered with air motor options. Air motor benefits include: No electrical connections and associated complexities. Pump speed is easily controlled by regulating the air pressure. The pump can be run from a nitrogen bottle during maintenance or emergencies. Air motors run cooler than ambient temperatures. Air motors are lighter weight than their …


Graphite – Non-Wetting in Molten Zinc

Graphite is a fantastic refractory material. Graphite’s characteristics include a very low thermal coefficient of expansion, high-temperature tolerance, light weight, and relatively low cost. There are other materials that can be used to build zinc pumps such as MoW or Moly-Tungsten, but the MoW is very expensive and hard to work resulting a pump that is …


3-Phase Motor Running Backwards? Updated 28-Jan-2016

Updated 28-Jan-2016 Editors Note: This post is one of the most frequently viewed on our website. This can be attributed to the high frequency of worn and damaged wiring. With proper electrical maintenance and pump startup procedures, this problem can be 100% eliminated.  3-Phase Motors used on Molten Metal Pumps Nearly all the electric motors …


Why should I use a circulation pump? Updated 25-Jan-2016

Updated 25-Jan-2016 Early Reverb Furnace Designs The reverberator (reverb) furnace has been in use since medieval times. This diagram shows a primitive reverberatory furnace of an early design. The entire furnace could be constructed from natural refractory materials such as clay. This design has a range of limitations that has led to the modern reverb furnace. For …


Re-use of a Graphite Pump – Not a Warped Idea – Update 11-Jan-16

Updated 11 January 16 Unlike stainless steel pumps, graphite pumps can be quickly and easily reintroduced into the molten metal bath, and the pump will operate with the same efficiency as when removed from the melt. This capability is because graphite retains its structural and dimensional integrity while stainless steel becomes flexible and deforms at …


Dross Pumping Best Practices – Updated 6 Jan 2016

Update: 6 January 2016: Using a dross pump is not the same as using a vacuum cleaner, although there are some interesting comparisons (which I will leave up the reader’s imagination.). In this post, I will discuss some best practices for zinc dross pumping. Why pump dross? It’s all about zinc pot down time. Dross …
