Whether your castings were poured in our sand foundry or elsewhere, we have the capabilities to deliver them as semi-machined, finish-machined, or as an assembly.

We can finish machine, keyway, balance, and assemble your impellers.

We have the unique capability to machine keyways up to 4.5 inches wide and 40 inches long; we are frequently contracted by other machine shops to complete such work.
