Dayton double diaphragm pumps are suitable for general pump transfer, recirculation, spraying, dispensing, filling, fuel evacuation, low scheming transfer and rough metering dewatering applications. They feature cast iron construction for wear resistance & vibration dampening, and spring assisted air valves that do not require lubrication for rapid discharge of the media present in pipelines. These pumps can run dry and have the capability to pump solvents, slurries & high viscosity liquids such as waste oils & paints. They have NPT, flange & Tri-Clamp connections for secure seals and transportation of liquids with minimal risk of contamination. Choose from a broad range of these pumps, available in PTFE, Buna-N, santoprene (R) and EPDM ball variants.
