A larger, higher power turgo runner size is now being produced by Hartvigsen-Hydro of the USA and Cargo & Kraft of Sweden.
Hartvigsen-Hydro together with Cargo & Kraft are now offering precision cast turgo type turbine runners and buckets suitable for use with nozzles up to 50 mm (2 inches). These turbine buckets are cast from a high tensile strength stainless alloy and are suitable for higher power micro hydro installations to low end small hydro. Complete custom runners start from 720 USD. Turbine bucket sets are also sold separately for 24 USD each. These turbines are a 150% scaling of the popular orange turgospoons.
