The work is mostly rebuilding worn journals, fits and housings so the rotating assembly runs true again.

Stock photo: the chuck and turret of a CNC lathe A pump or turbine is a shaft with things bolted to it: bearings, a seal, an impeller or a rotor. Wear shows up at the places where those parts meet the shaft and the casing. Our services list includes shaft, turbine and pump repair for a geothermal power plant, and pump repair and fabrication for water and power companies. ## At a glance - Shaft, turbine and pump parts repaired - Pump repair and fabrication for water and power companies - Journals and seal areas rebuilt by metal spray - Balancing arranged with an outside shop after machining I have used Wolf Machine several times over the past few years for fabricating and repair of parts on my ultralight aircraft. [...] These guys are great to deal with. I wouldn't take my projects anywhere else.

Repairing the shaft and fits gives the plant the same pump back instead of waiting on a new one. That is the situation behind two kinds of work we do: shaft, turbine, pump and related parts repair for a geothermal power plant, and pump repair and fabrication for water and power companies. ## How a worn shaft is brought back A journal worn under a bearing or a groove cut by a packing or seal is built up, then turned to size. [Metal spray](https://wolfmachinenv.com/services/metal-spray/) suits these surfaces well because it adds metal without putting weld heat into a long, slender shaft. Stainless and bronze parts get the same attention to fit as steel ones. Before a costly shaft is rebuilt, a [Magnaflux check](https://wolfmachinenv.com/services/magnaflux-inspection/) on magnetic shafts rules out cracks at keyways and shoulders. When a shaft is not worth saving, a new one is machined from the old part or a drawing. ## Balancing Pump impellers and turbine rotors turn fast, so balance matters after machining. We arrange that with an outside balancing shop once the machining is finished. ## Matching the original fit The aim on every pump or turbine part is the fit the machine was built with: the right diameter under the bearing, the right seat for the impeller, the right clearance at the wear ring. Bring the worn part and any part of the old drawing you still have, and the sizes can be taken from the part and from the mating pieces. ## What to send The pump or turbine type, the part name, the shaft material if known, and photos of the worn areas. A drawing helps, but a worn sample is enough.
