Runners according to your design
Forged monoblock Turgo runners from CNC TVAR
Rotor is the heart of any turbine. It is a center where the fluid strikes and the tangential force of the impact causes the shaft of the turbine to rotate, producing torque. Close attention to design of blade angles at inlet and outlet is necessary, as these are major parameters affecting power production. This is why CNC TVAR manufactures all runners from a forged blocks consisting of premium alloys no matter the number of blades, size, or rotor design. We understand the need for the highest possible efficiency and make sure, it is not just on the paper. Thus, CNC TVAR provides a long-lasting, high-quality product.
