Replacement mounting pin manufactured by Canyon Hydro

This replacement mounting pin for a Pelton runner was manufactured by Canyon Hydro. The pin measures about 300mm (12 inches) long.

All major turbine components can be repaired or replaced by Canyon, including runners, nozzles, wicket gates, and wear rings. Canyon also provides onsite services, including precision line boring.  

Three-dimensional models are created from CAD drawings, laying the groundwork for patterns and castings.  Runner castings are tightly controlled, following rigid specifications for alloys, chills, core assemblies, and other requirements.  Before the runner is released for final machining and balancing, it undergoes non-destructive testing and heat treating. 

Canyon Hydro maintains an impressive array of high capacity, precision machinery, both conventional and CNC-controlled. We've recently doubled the capacity at our dedicated CNC facility. Our largest CNC mill is a 7-axis machine able to accommodate components up to 3 meters (16 feet) diameter, 11 meters (36 feet) long, weighing up to 15 tons.

Canyon Hydro's CNC machining center

Canyon's CNC Center provides a broad array of precision machining capabilities, including the large-capacity CNC mill at left.

For more information about Canyon's machining abilities, see our table of maximum capacities.

Our goal at Canyon Hydro is to build replacement components that deliver more power and last longer than your originals. Please contact us if you would like more information or a quote.
