Corken Responds to Requests For New Autogas Pumps Corken asked, Corken listened Through the help of surveys directed towards marketers promoting autogas, designers and installers of autogas systems, and service personnel responsible for the maintenance of autogas systems, the following concerns surfaced frequently: "Need a pump capable of delivering a minimum of 1 lpm at 7 bar." "Due to system restrictions, the industry is looking for a pump that pumps 75 to 8 lpm at 1 bar." "Noise is an issue. Many autogas stations are in the metropolitan area. People want to fill fast and quietly. Also, the neighbors do not like irritating noise." Corken develops a new pump. Corken took on the challenge to meet the needs as defined for a new autogas pump. The results are the Autogas Series which achieves new levels of performance with higher flows at high differential pressures, nonpulsating and quiet transfer, longer pump life and a design that is easy to repair. "My pumps require a lot of maintenance. Need a pump that will last longer and when it needs service, it needs to be simple and something we can repair quickly. Down time can not be tolerated in autogas markets." The Coro-Flo 15 model pumps are the new standard for autogas delivery. 85 LPM at 1 Bar @ 288 RPM 174 LPM at 2 Bar @ 288 RPM Ideal for Dual Hose Dispensers and Multiple Dispensers Heavy Duty Bearings Single Mechanical Seal Floating Impeller Continuous Duty Capability Ductile Iron Case ANSI or DIN Flanges Metric Fasteners Replace Seal in Minutes Three Mounting Options Designed for 5 and 6 Hz 3

More Quality LPG Products From Corken Medium differential regenerative turbine pumps... The Coro-Flo pumps have a history of excellent reliability for applications requiring low flows at medium differential pressures. Typical applications are cylinder filling, forklift filling, and vaporizer feed. Multistage side channel pumps... The SC-Series exceeds expectations in the handling of liquids involving high differential pressures, low NPSH conditions, and aerated liquids. The pumps are used in carousel filling, bulk transfer, and pumping from underground storage. Stationary vane pumps... The Coro-Vane line is recognized as a pump in which its pumping efficiencies remain high throughout the life of the pump. The sliding vanes compensate for wear and wear parts are easily replaced. The pumps are used for bulk transfer of liquefied gases. Truck vane pumps... The new generation of Z-Series pumps quickly proved to be a pump that held up to the demanding needs of fleets hauling liquefied gases and has far surpassed sales expectations. Pumps are available for PTO drive and hydraulic drive. Vertical compressors... The oil-free, highly reliable vertical reciprocating compressors are extremely versatile and are used to transfer LPG between tanks, off-load and load-out LPG, recover residual vapor and evacuate vapors for maintenance purposes. Typically they are used to unload barges, rail cars, transports and LPG delivery trucks. In many countries a compressor is used to off-load LPG at the autogas stations. Horizontal compressors... The Corken horizontal compressor is perfect for the terminal requiring transfer of large volumes of LPG. This heavy-duty, balanced-opposed gas compressor offers smooth, reliable transfer from barges and multiple rail cars. Vacuum pumps... The Coro-Vac Series is used for evacuating air from new LPG cylinders and bulk tanks. In many countries air is removed by purging LPG through the cylinder several times. The Coro-Vac eliminates the need to waste and vent gas to the atmosphere which enhances safety and saves time. 6
