Corken's regenerative turbine industrial pump is known as a Coro-Flo®. The Coro-Flo turbine pump is a continuous duty design and is a great choice for lower flows and moderate to high differential pressures. The liquid is circulated between the teeth of an impeller that rotates between the pump casing and head. Since the Coro-Flo is designed with a free-floating impeller, there is no metal-to-metal contact so the maintenance requirements are minimized. Corken offers several models of regenerative turbine pumps for wide range of differential pressures, and capacities.
Corken's Coro-Flo turbine pump was originally developed to fill propane cylinders. Over the years it has found its way into many other applications—especially where volatile liquid transfer is involved. It is commonly used as a vaporizer feed pump, aerosol propellant pump, and propane cylinder filling pump. Suitable for light liquids such as gasoline, solvents, and light oils and liquefied gases such as ammonia, carbon dioxide, sulfur dioxide, propane, butane, and refrigerant gases.
