The pumps of the DENG series are positive displacement metering pumps to hydraulic cylinders, pneumatically driven. Its main fields of application are in gas processing, methanol and corrosion inhibitors injection and various processes specific to the oil industry. They have the capacity to dose at high pressure (up to 12000 PSI). They are simple to operate and their compact and robust design minimizes the necessary maintenance. Thanks to the regulation of suction and injection speeds, are particularly suitable for dispensing liquids of low vapor pressure. There is an optional version that can handle sour gas.
