Corken has served the liquefied petroleum gas (LPG) industry since the mid-1940s. LPG is a flammable mixture of hydrocarbons gases commonly known as propane and butane. These gases fuel vehicles, warm homes and businesses, and cook foods all around the world. Through the years, Corken developed a wide variety of compression and pumping solutions for autogas filling stations, bulk plant, tank car unloading, propane delivery truck, propane transport, and agricultural agricultural ammonia transport applications.
Each compressor and pump comes with a standard mounting. If the standard mounting does not meet the requirements for the application, Corken can modify it or design a custom engineered package from the floor up.
LPG Stationary
And Truck Pumps
Corken offers several models of sliding vane and regenerative turbine designs for a variety of LPG and agricultural ammonia applications. Each technology offers a wide range of differential pressures and capacities for bulk plant, propane delivery truck, and transport applications.
Sliding Vane Pumps
Corken’s positive displacement sliding vane pump is known as a Coro-Vane® and is an excellent choice for high capacity applications.Technical Details
Regenerative Turbine Pumps
Corken’s regenerative turbine pump is known as a Coro-Flo® and has a strong reputation in the LPG industry for being a long lasting pump. The free-floating impeller helps minimize wear and delivers years of trouble-free service.
