PVDF air operated double diaphragm pumps can transport high viscosity fluids such as paint, sludge and sewage, but the flow rate and pressure depend on the actual application. If you have any questions about compatibility with high viscosity fluids, please call our application experts for more information.
鈼?PVDF air operated double diaphragm pump can deliver fluids with viscosity up to 11,000 cp.
鈼?Air motor eliminates sparking problems associated with electric pumps.
鈼?Bolted pump design provides easy access to the pump head for maintenance and maintains a seal after repeated repairs.
鈼?This product is also suitable for low abrasive portable fluids, suspended solids.
鈼?Safe Handling鈥擣or high viscosity and shear sensitive materials.
鈼?The encapsulated muffler provides excellent noise reduction.
Operating principle
Two diaphragms connected by a diaphragm rod work together to create fluid motion in the pump. One side is in suction mode and the other side is in discharge mode. The inward movement of the diaphragm creates suction that brings the balls closer together. When this happens, the top valve closes and the bottom valve opens, which allows fluid to enter the chamber through the bottom port. The outward movement of the diaphragm induces a discharge motion that causes the spheres to move away from each other. At this point, the top valve is open and the bottom valve is closed. This allows fluid to flow out of the chamber and out through the top port. The process alternates between the two chambers in a continuous cycle. The pump diaphragm is driven by compressed air, and the movement of the main air valve drives the compressed air to move left and right.
