For dual hose Autogas dispenser applications, sliding vane positive displacement pumps are quickly becoming the pump technology of choice worldwide because they offer performance, reliability and financial benefits over other high differential LPG pump technologies. Sliding vane pumps are capable of overcoming many of the challenges that plague other Autogas-type pumps, such as inconsistencies in mixed LPG composition, line pressure changes, entrained vapors, vapor lock and temperature changes. In addition, sliding vane pumps offer a lower upfront cost, are safe and easy to install and maintain, and provide high efficiency and reliability even for the most active Autogas fueling operations.
