Impeller Types and Purposes

Three Main Types of Impellers We offer three different types of impellers for many of our molten metal pumps. (The impeller is the vaned wheel that spins inside the pump base.) The impeller and its interaction with the pump base (and base volute) largely determine the performance characteristics of a given pump design. Each impeller ...

Small Pump Well? You need a Chameleon!

Pump Well Size A recent survey of installed aluminum reverb furnaces found that most included a pump well only large enough for a properly sized circulation pump. With manufacturing floor space at a premium and furnace prices increasing, it is no surprise that the pump well would be kept to an absolute minimum. There is …

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 …

Like a Launder, Only Better!

A launder is used to transport molten metal. The basic construction of a launder is a steel trough lined with refractory material to insulate the molten metal from the steel. (Insulating both thermally and chemically.) The molten metal will lose heat as gravity draws it down the launder. If the heat is lost too fast, …

NEVER RUN A PUMP DRY!

The molten metal IS the lubrication for the impeller and base-volute. Running the pump dry will result in damage. The only question is how much damage. This impeller is an example of a very costly mistake. A broken impeller is probably the best possible outcome of running a pump dry. Most likely, the damage would …

Pre-Storage Pump Inspection – Maintenance Pumps

Factory Evaluation Any or all components can be sent to High Temperature Systems, Inc. for inspection and evaluation. The most accurate evaluation requires complete chemical removal of the metal from the graphite surfaces. This is especially true for proper inspection of the pump base. Contact High Temperature Systems, Inc. prior to shipment of any components. …

Preparing the Pump for Storage – Operational Assessment and Removal from Metal

Operational Assessment – Before Removing the Pump from the Metal About 10% of pumps are used exclusively for scheduled furnace maintenance. Between usages, these pumps need to be properly stored and maintained. The first step to good pump maintenance is an operational assessment. Study the pump’s operation prior to de-energizing and removal from the molten …
