New stainless-steel pumps provide pharmaceutical systems developers with the most effective air-operated double-diaphragm (AODD) pump solution for the transfer of carbon slurry. The pumps feature manufacturer’s patent-pending Pro-Flo X™ air distribution system (ADS), which offers operational flexibility in carbon slurry transfer applications. This flexibility is accomplished by the state-of-the-art Efficiency Management System (EMS™), which optimizes the Pro-Flo X™ ADS for the actual operation parameters regardless of the application demands or pump size. The management system allows the operator to use an integrated control dial to select the efficiency point and flow rate that best suits the application. The AODD pumps are powered by natural gas and have been tested and certified by CSA International for use in applications where compressed natural gas is the energy source and the driving force of the pump. The pumps come with a blue serial number tag for easy identification in the field and also include a caution sticker that details specific safety information, and the appropriate CSA certification logos.
