MAIN FEATURES

DELLMECO air operated diaphragm (AODD) pumps are suitable for a wide range of applications. They have a high abrasive resistance and withstand aggressive chemicals including acids, oils, solvents, paints, sludges and even media containing solid particles such as found in waste water. These pumps can also be used for transferring powders. All the pumps are self-priming and the capacities and pressure can be easily controlled. This pump is a positive-displacement pump that transfers fluids by means of diaphragms movement operated by compressed air. The casing in contact with the fluid is made of PE (polyethylene), PE conductive, PTFE (polytetrafluoroethylene), PTFE conductive.

Designed to succeed – temperatures up to + 120°C – pressure up to 14 bar – lubrication-free operation – low air consumption – abrasion resistance (PE, PE conductive)

Flexible installation – BSP as standard – PN10, PN16, ANSI, NPT, JIS, RJT, split manifold configurations available – connections may rotate 180°

Solid, compact and strong – housing machined from solid PE, PTFE as well as conductive PE and PTFE – withstands aggressive chemicals – gentle pumping action – viscous media transfer

Perfect diaphgram – completely smooth liquid-side surface (no holes) – no metal in contact with the media – materials made to match the application
