Francis runner

Runner

Movable parts of the turbine that transmit the movement of the water to the shaft to which they are attached to turn the rotor.

Pelton runner

A complex but cost effective solution for the hydro market

Type of runner that is suited to high water sources (usually over 1,000 ft) and low flow rates.Pelton Turbines utilize a paddle design and use the motion of the water to extract energy. When our competitor was supplying Pelton Wheels to customer, the customer was spending up to 120 hours in weld repair per casting to make the product usable. A change to this product reduced weld upgrade time by 90%+ for true, measurable cost and time savings.

Kaplan runner

Type of runner that is suited to low heights of water (usually between 30 and 200 ft) and variable flow rates.

Kaplan turbines convert potential energy to mechanical energy. This type of turbine is classified as a reaction turbine, as it operates within a pressure system and relies upon a continuous body of water from the suction to pressure side of the turbine.

Francis runner

Most common type of runner that is suited to average heights of water (usually between 100 and 1,000 ft).

Popular Francis Turbines feature an inward flow reaction to spin the turbine and count on consistent material and fin profiles to operate efficiently. Large intricate cast components produced by our production division help drive those applications. Hydro manufacturers and operators also rely on wear rings, seal rings and shaft sleeves from other divisions.

Blade

Stationary curved plate on the turbine’s runner; it receives the thrust of the water to turn the runner.

Ring

Circular part that supports the wicket gates.
